The aggressive customer. A special breed, and a growing problem for anyone behind a till, counter or bar. I first met one as a teenager working in hospitality. No game plan, no training and no thick skin. Swimming without armbands, and everyone acted as if that was just part of the job.
These days I know better. It isn't part of the job. In the Netherlands, supermarkets, retailers and hospitality businesses raised the alarm together during Safety Week 2025. Aggression towards staff is on the rise. You can prepare your team for it, though, long before the first customer raises their voice.
Five tips for dealing with aggressive customers, from the first agreement to the aftercare.
What can a customer say or do, and what crosses the line? If your team has to decide that for themselves, everyone picks a different limit. One swallows everything, another starts an argument. So agree together on what unacceptable behaviour looks like.
Do it with a small working group. Bring in people from the shop floor who have dealt with this more than once. They know which kind of complaint usually tips over.
Nobody reads a hundred-page escalation plan. Certainly not with an angry customer in front of them. Keep the plan short and visual. Who does what? When do you call your manager? And when do you call the police?
Put the plan on your people's phones, with short videos instead of a handbook. An employee who hesitates can pull it up in a few taps.
An angry customer in front of you, a queue that keeps growing and a colleague who has just gone on break. That is not the moment to work out what to say for the first time. Strong teams rehearse it in advance. Act it out with a colleague, or watch a short video of a customer losing their temper. Then look at it together: what could you have said instead?
Circle K built a whole programme around it, on emotion and aggression from guests. Staff learn to recognise tension, prevent aggression and practise with video clips. More than 1,300 employees have access to it, and of those who start, 94 per cent finish.
An employee who stays quiet after an incident carries it alone. And the next colleague walks into the same trap. So make it easy to report incidents, anonymously too.
Discuss them in team meetings or the morning huddle. What went well? What will we do differently next time? That way the whole team learns from one incident. As a manager, that can be a difficult conversation, especially if it's still bothering a colleague.
An aggressive incident doesn't end when the customer walks out. Your employee takes it home. Make sure a manager is reachable straight away. Agree who calls, who looks after the colleague and where someone can turn for extra support.
Circle K gives aftercare a module of its own: what do you do after an aggressive incident? Review your protocol regularly, together with the people who use it. Good aftercare is also one of the best ways to keep people on board for longer.
A team that stays calm at the toughest moment gives customers a better experience, and stays longer itself. Want to know how your team can practise this before anything goes wrong? We will show you in half an hour how other retailers tackle it.
