In every shop the moment comes when a customer brings something back to the counter and says: "This isn't right." The yoghurt is out of date, the bread is mouldy, the till charged more than the shelf said, or they simply feel someone was rude to them yesterday. Behind the counter it is easy to get defensive — especially with a queue waiting and a complaint that seems unfair.
But in a small shop a complaint is not the worst case, it is a second chance. Someone who speaks up still wants to come back — someone who says nothing simply shops elsewhere next time, and you never find out why. After a well-handled complaint a customer is often more loyal than before, because they have seen that their word counts in the shop.
This article is a practical guide for behind the counter: what to say in the first minute and what never to say, what to do in the six most common cases, when to exchange, when to refund and when to give a credit, up to what value an assistant can decide alone, and how to say no when someone takes advantage of your goodwill. At the end you get a five-minute weekly routine for learning from complaints.
Why handling complaints well pays off
At the moment of a complaint, the stake seems to be the price of one product. A yoghurt, a loaf, a wrongly rung-up item — a few units it would be a shame to "just give away". The real stake, though, is not those few units but where the customer will shop over the coming months.
Take a round example in neutral units. A regular comes in four times a week and spends 15 units each time. Over a year, counting fifty weeks, that is 3,000 units of turnover. If your shop's average margin is 25 per cent, roughly 750 units of that stays with you. The yoghurt being complained about costs 1 unit. If the argument makes this customer start shopping elsewhere, you haven't saved 1 unit, you have lost 750 — and that doesn't yet count what they tell the neighbours about the shop.
This doesn't mean giving everyone everything. It means that with small items an argument almost always costs more than giving way, and that your attention belongs where there really is a suspicion of abuse. In the vast majority of cases the customer is right, or at least acting in good faith — and that is the case the shop needs to handle well, not the rare exception.
The first 60 seconds
Handling a complaint doesn't start with the solution, it starts with listening. A customer bringing something back is often already tense: it is awkward for them to have to speak up, and they expect an argument. If your first sentence breaks that expectation, the rest of the conversation becomes much easier. Four steps, in this order:
- Listen to the end. Don't interrupt, even if you know what happened from the first sentence. The customer needs to say it — that is half the complaint.
- Don't argue. Not even if you think they are wrong. In the first minute the goal is not to establish the truth but to let the mood settle.
- Thank them for telling you. This is not a polite formula: it really is better that they told you rather than the neighbour or the internet.
- Sum it up in one sentence. "So you bought it yesterday, and this morning when you opened it, it was already sour." The customer sees you understood, and you can be sure you understood correctly.
Only then turn to the solution. If the customer answers your summary with "yes, exactly", the hardest part is over — from here most cases can be closed in a sentence. The table below shows which sentences help, and which can turn a simple exchange into a row.
| Say instead | Never say | Why |
|---|---|---|
| "Thank you for telling me, we'll put this right." | "That's never happened here before." | The customer isn't interested in statistics, only in their own case. Denial tells them you don't believe them. |
| "That really is annoying, I'm sorry." | "I wasn't on shift." | The customer is talking to the shop, not a person. Passing the blame on signals helplessness. |
| "Shall I get you a fresh one, or would you rather have your money back?" | "Are you sure you bought it here?" | A choice reassures, suspicion offends — even when the question might be fair. |
| "Let me look at the receipt so I can correct it exactly." | "Without a receipt I can't do anything." | The receipt helps, but it isn't a condition for everything. Say first what you can do, not what you can't. |
| "I'll tell the owner so it doesn't happen again." | "That's the supplier's fault, not ours." | The customer took it off the shelf; to them, the shop is responsible. You sort it out with the supplier, not them. |
| "I understand that was frustrating." | "Calm down." | Nobody calms down because they are told to. Acknowledgement, on the other hand, genuinely soothes. |
| "I can't help with that right now, but let me tell you what I can do." | "That's the rule, I didn't make it." | A no can be explained and closed with an alternative too. Pointing at the rule doesn't end the argument, it only postpones it. |
„A customer who complains still wants to come back. One who says nothing is already shopping elsewhere.”
Typical cases and what to do
In a small shop, complaints fall into surprisingly few types. If everyone knows the answer to the six most common, the assistant doesn't improvise, and the customer gets the same treatment whoever is behind the counter.
| Case | What to do | How to record it | What to check afterwards |
|---|---|---|---|
| Out-of-date product on the shelf — the customer noticed at the till or at home | Thank them, and immediately give them a fresh one or refund the price. If it comes up at the till, simply fetch a fresh one from the shelf. | Record the out-of-date item as waste with the reason "expired"; handle the money at the till according to local rules. | Check the whole shelf the same day — where there is one out-of-date item, it is rarely alone. |
| Spoilt or faulty goods — mouldy bread, sour milk, broken eggs | Exchange or refund, without questions. If the fault is obvious, don't necessarily ask for the receipt either. | Waste with the reason "faulty" or "spoilt"; set the product aside if you want to take it up with the supplier. | If the same product keeps coming back, look at the supplier's batch or at how it is stored. |
| A different price at the till than on the shelf | In many places the customer can ask for the displayed price. Best practice: give the shelf price, and correct the price label or the till the same day. | Record the refund of the difference at the till according to local rules. | Was a label left up after a promotion ended? On price-change days, always check the shelf as well. |
| A dispute over change | Don't argue at the counter. Say you will count the till at the end of the shift and return any surplus — and take the customer's contact details. | Note the time and the amount, and check it during the till reconciliation at shift close. | If it happens often, slow down handing out money: put the note you received into the drawer only after giving the change. |
| Rude service | Apologise on behalf of the shop, and don't ask who it was. Say you will look into it. | Write it in the complaints notebook: when, what happened, in the customer's words. | Talk it through with the assistant in private, not in front of the customer. Listen to them first too. |
| Missing product — "it was always here, now it isn't" | Tell them honestly when it will be back, or suggest a substitute. If the customer buys it regularly, set one aside for them from the next delivery. | Write the product's name in the complaints notebook. | If a product regularly runs out, the order quantity needs adjusting. |
An out-of-date product is the most awkward case, because in the customer's eyes it is not one item that is at fault but the whole shop that is careless. Here it is worth adding a small gesture to the exchange and, even more importantly, checking the whole shelf that day. Keeping out-of-date stock off the shelf isn't solved after the complaint but with a daily routine — our article Date codes in the shop: the rotation that prevents waste covers this in detail.
Exchange, refund or credit
The three solutions are not equivalent, and it matters which one you offer first. It is best if the customer can choose, but the assistant needs to know which one suits which case, and what trace each one leaves.
| Solution | When it works | What to watch |
|---|---|---|
| Exchange | For faulty, spoilt or out-of-date goods, if there is a good item on the shelf and the customer wanted it anyway | The simplest and quickest. Record the returned item as waste; the replacement is not a new sale. |
| Refund | If there is nothing to exchange, the customer no longer wants the product, or the fault has cost it their trust | The refund has to be handled at the till according to local rules. Make a note so no unexplained shortfall is left at shift close. |
| Credit | If the customer doesn't want anything else right now but will be back — for example an amount noted down for their next purchase | Offer it only if you can keep track: note it with the name, date and amount. A customer can't be forced into it if they ask for their money back. |
| A small gesture alongside the solution | If the shop made a mistake and the customer was put out — an out-of-date product, rude service | A pastry or a coffee is not about the money but about showing the shop takes it seriously. It doesn't replace the exchange, it accompanies it. |
When recording, two things have to be handled separately: the goods and the money. The money — the refund or the price difference — belongs in the certified till or whatever device you use to issue receipts, according to local rules; your accountant can tell you how it has to be done where you are. The returned, unsellable goods, on the other hand, are waste, and should be recorded as such, with a reason. In Boltom App this is the same waste recording as for bakery goods thrown out after closing — but it doesn't replace the financial record of the refund; that comes from your till.
- Never put returned, out-of-date or faulty goods back on the shelf, or mix them with good stock. Keep a separate, labelled box in the stockroom.
- Record them as waste and choose a reason: expired, spoilt, damaged, returned by customer. At the end of the month the reason is worth more than the figure itself.
- If you want to take it up with the supplier, set the product aside with its packaging and the receipt, and write the date on it.
- Note any cash refunded during the shift, so it doesn't turn up as a mystery at the till reconciliation.
- If the customer got an exchange, don't ring up the replacement again as a sale — it took the place of the returned item.
Up to what value can an assistant decide alone
One of the most common weak spots in complaint handling is not knowledge but authority. If the assistant doesn't know whether they are allowed to refund the price of a product, they either phone someone, stall, or — in the worst case — say no, because they think they can't go wrong that way. Meanwhile the customer waits, and sees that nobody behind the counter can decide anything.
The answer is a simple limit, stated in advance. For example: anyone at the counter can decide on exchanging or refunding the price of an item up to a set amount — say 10 units. Above that, or if abuse is suspected, the assistant notes the case down and the owner decides. You set the limit to suit your shop's price level, but it should be stated out loud and written down.
- They can always give an exchange for faulty, spoilt or out-of-date goods, whatever the amount — that is the shop's mistake.
- They can give a refund alone up to the set amount; above it they note the case down and check with you.
- They are free to give a small gesture — a pastry, a coffee — if the shop got something wrong.
- They are also allowed to say no if they see abuse, but then they should always note it down, and the owner should look at it later.
- They should never have to make a phone call in front of the customer just to refund the price of one product.
When you don't have to give way
Goodwill doesn't mean accepting everything. Some people regularly bring back half-eaten goods, some complain about products bought in another shop, and some use a complaint to get something for free. These cases are rare, but every shop meets them — and if the assistant doesn't know how to say no, they either always give way or start suspecting everyone.
| Sign | What it may mean | How to respond |
|---|---|---|
| The same customer complains every week, always about a different product | It may be chance, but it may be a habit | Give way the first few times, but note it down. If the pattern is clear, the owner should talk to them, calmly and in private. |
| A mostly eaten product, with "I didn't like it" | Not a fault but taste — this isn't a complaint | Explain politely that you exchange faulty goods, but can't take back an opened product that is in good condition. |
| A product the shop doesn't even stock | A mistake or a try-on | Show them in a friendly way that you don't carry this product, and offer to help work out where it came from. |
| A high-value complaint with no receipt or packaging | There is no way to check what happened | Say you can't decide on an amount that size alone, note the case and the contact details, and the owner will call back. |
| Pressure, shouting, threats about reviews | The complaint has become a tool, not the goal | Stay calm, repeat what you can offer, and don't give more because of the volume. If the situation turns threatening, safety comes first. |
A polite no has three parts: you name what you acknowledge ("I understand you didn't like it"), you say what you can't do, with a short reason ("I can't take back an opened product because I can't sell it again"), and you offer what you can ("but if you're not sure next time, I'm happy to suggest something else"). That way the no is aimed at the request, not the customer — and the customer can leave without feeling humiliated.
Written complaints, complaints books, online reviews
Most complaints arrive verbally and are settled verbally. Sometimes, however, a customer wants to put their complaint in writing, or local rules expressly allow for this. In many countries some form of complaint-handling tool is mandatory in a shop — a complaints book, a complaint form or a written complaints procedure — and in many places the customer must be told where they can turn.
- Know whether a complaints book or another written complaint-handling tool is mandatory where you are, and if so, where it has to be kept and how it must be handled.
- If you have one, keep it available at the counter at all times, and make sure the staff know where it is. A complaint that can't be written down is two complaints.
- Answer a written complaint within the deadline set by local rules, and keep a copy of your reply.
- Don't correct or comment on the customer's complaint on the spot. The reply should be factual, thank them for raising it, and describe what you did.
- Display on the door or at the counter where a dissatisfied customer can turn — where this is required, it is not a courtesy but an obligation.
When the complaint arrives online
More and more complaints appear not at the counter but among the shop's online reviews. That is more unpleasant, because everyone can see it, but it is also an opportunity: a well-written reply to a negative review says more about the shop than ten words of praise. New customers looking up the shop often read the replies rather than the reviews. Keeping the shop's profile in order is covered in our article How people find your shop on Google Maps and in search.
- Reply within a day or two, but not straight away and angrily. Read it, wait an hour, then write.
- Thank them for the feedback, and if the shop made a mistake, acknowledge it simply, without excuses.
- Describe what you did or will do: "since then we check the dairy shelf every day".
- Invite the customer to talk it over in person, or to find you in the shop — don't go into the details in the public reply.
- Never argue in public, and never post personal details about a member of staff or the customer.
- If the review is clearly not about your shop, or is abusive, use the platform's reporting option, but keep your reply polite even then.
Learn from complaints: five minutes a week
One complaint is a case, two are a signal, and three are a process that needs fixing. To see this, complaints have to be written down — not to hold someone to account, but so the pattern shows. A notebook under the counter is enough, one case per line: date, what happened, what you gave, who handled it.
Once a week, after closing, take out the notebook and the waste list for five minutes. No analysis needed, just three questions: what happened more than once, which product keeps coming back, and was there a case the assistant couldn't resolve alone. The typical patterns and their fixes:
- Recurring out-of-date products: rotation isn't working. It is worth going through the shelf-filling routine and the daily date check again.
- The same product spoils repeatedly: the supplier's batch, the fridge temperature or the order quantity is the problem.
- Price disputes at the till: the price labels and the till prices aren't updated together. On price-change days, both need doing at the same time.
- Change disputes: the way money is handed out needs slowing down and standardising.
- Complaints about service: a conversation, not a punishment. The assistant often doesn't even know something came across badly.
- Missing products: adjust the order list, or set one aside for the regular.
Putting it in place step by step
- 11. Write down the six typical casesUsing the table, write down what you do for out-of-date goods, spoilt goods, a wrong price, a change dispute, rude service and a missing product. Keep it to one page, in simple sentences, in your own shop's words.
- 22. Set the authority limitUp to what amount can an assistant decide alone, and what do you always decide yourself? Write it down, and say it out loud to the team too — a limit only you know about is not a limit.
- 33. Make a place for returned goodsA labelled box in the stockroom, and a clear rule: what comes back doesn't go back on the shelf, and always leaves as waste, recorded with a reason.
- 44. Clarify the financial sideAsk your accountant how refunds and price differences have to be handled at the till where you are, and what applies to a complaints book or complaints procedure. You only need to find this out once; after that it is routine.
- 55. Practise itAt a team meeting, act out two or three cases: one person is the customer, the other stands behind the counter. It is awkward, but ten minutes of practice is worth more than any written rule, especially for a new assistant.
- 66. Start the five minutes a weekPut a notebook under the counter, and go through it once a week together with the waste list. After the first month you can already see which complaint keeps recurring — and which has disappeared because you fixed its cause.

Frequently asked questions
Do I have to take a product back if the customer has simply changed their mind?
This differs from country to country, and also depends on where and how the purchase was made, so the exact rule is worth checking with the local consumer protection authority. In many places there is no obligation to take back faultless goods bought in a shop, and food especially not. You can still decide to take back an unopened, undamaged product out of goodwill, especially from a regular. What matters is that your rule is clear and every assistant applies it the same way.
What should I do if a customer found an out-of-date product on the shelf?
Thank them for telling you, and immediately give them a fresh one, or refund the price if that is what they want. Don't make excuses or look for someone to blame in front of the customer — this is the shop's mistake, and the customer can see that clearly. Record the out-of-date item as waste with the reason "expired", and check the whole shelf that same day. If it happens more than once, the rotation routine needs going through again with the team.
What should I do if the till charged a different price from the one on the shelf?
Best practice is for the customer to get the price displayed on the shelf, and in many places the rules require this too. Refund the difference, and record the money at the till according to local rules. Correct the price label or the till price the same day, depending on which one is right. The most common cause is an expired promotion whose label was left up, so on price-change days always check the shelf as well.
Do I have to refund the money, or is an exchange enough?
For faulty, spoilt or out-of-date goods, in most places the customer can choose, and if they want their money back it isn't worth refusing — the local authority can tell you the exact legal position. In practical terms too, offering a choice is best: offer both the exchange and the refund, and leave it to the customer. A credit only works if the customer asks for it and you can write it down. Never push an exchange on someone who no longer trusts the product.
What should I do with returned, unsellable goods?
Never put them back on the shelf or mix them with good stock. Put them in a separate, labelled box in the stockroom, and record them as waste with a reason — for example expired, spoilt or returned by customer. If you want to take it up with the supplier, keep the item with its packaging and the receipt, and write the date on it. If it isn't recorded, it shows up as an unexplained shortfall at the end of the month.
Up to what amount can an assistant decide alone?
You have to decide this based on your shop's price level, but there should be a limit that is stated and written down. A rule that works well: they can always give an exchange for faulty goods, a refund up to a set amount on their own, and above it they note the case and you decide. The limit should be large enough to cover ninety per cent of everyday cases. If you have to be called for every complaint, the customer waits and the assistant won't take responsibility either.
How do I handle a dispute over change?
Don't argue at the counter, because neither of you can prove your case there. Explain calmly that you will count the till at the end of the shift and return any surplus — take the customer's contact details, and note the time and the amount. At shift close, the till reconciliation will show whether there was a surplus. In the longer term you can prevent it by putting the note you received into the drawer only after handing out the change.
What should I do if a customer shouts or is abusive?
Stay calm, speak more quietly, and don't take on their tone. Repeat what you can offer, and don't give more just because of the volume, because that teaches them for next time. If the situation turns threatening, your safety and that of other customers comes first: ask for help, and don't stay alone in the situation. Afterwards, write down what happened and talk it over with the owner.
How do I recognise someone abusing complaints?
Almost never from a single case — the first time, good faith is the starting point. The signal is the pattern: the same customer regularly returns a different product each time, complains about mostly eaten goods, or about a product the shop doesn't even stock. You only see this if you write complaints down. If the pattern is clear, the owner should talk to the customer in private, calmly, without accusations.
Does a shop need a complaints book or a written complaints procedure?
This differs from country to country: in some places a complaints book or another written complaint-handling tool is mandatory, in others it isn't. In many places the customer must also be told where they can turn, and written complaints have to be answered within a deadline. Check what is mandatory where you are with the local consumer protection authority or your accountant. If you have such a tool, keep it available at the counter at all times, and make sure every assistant knows where it is.
How should I reply to a negative Google review?
Within a day or two, but not straight away and not angrily: read it, wait an hour, then write. Thank them for the feedback, acknowledge simply if something went wrong, and describe what you have done since. Invite the customer to talk in person, and don't go into the details in the public reply. Never argue in public, and never post personal details about the customer or a member of staff.
How can we learn from complaints without looking for a scapegoat?
By writing the case in the complaints notebook, not a verdict: when, what happened, what you gave. In five minutes a week, look at what keeps repeating, and always ask what needs to change in the process — shelf filling, ordering, the way money is handed out. If a complaint is about a member of staff, talk it through in private, and listen to them first too. When the team sees that a written-down complaint leads to a fix, not a punishment, they will start writing them down themselves.
Say the product's name and it's there on the till.
Boltom App takes the work behind the counter off your hands. You find a product by looking at its photo or saying its name out loud — no codes, no scraps of paper. Whatever leaves the shelf or goes in the bin is recorded right there, not in a notebook. It works alongside your existing till, not instead of it.
- A quick code with a photo — or just say the product's name and the till finds it.
- Staff consumption in three taps, recorded under the person's name.
- Daily waste with its reason: expired, broken, unsellable — totalled up in money.
