When a customer gets too excitable, retail workers know the drill: call their manager over to handle it.
Each customer is different, and they each have their own intentions when they enter a store. Of course, most shoppers arrive at a store with a list and just go around and gather all the items they need. But others require more assistance than that. Maybe they have a return that they waited too long to bring back, or perhaps they’re looking for a really specific thing and can’t find it. You can try your best to help them out as a worker, but only managers can handle the biggest problem customers.
It seems like a lot of customers aren’t even interested in resolving their conflicts. A lot of them just want to vent for a while. A good supervisor can tell the difference between a person who just needs to let it out, and a person who’s being a menace. Managers also have the power to boot people from stores for life, which is an excellent option for a lot of these cranky consumers.
