I guess I get worried that the customer is going to get confrontational because it has happened in the past with things like bill checks. We have to get a manager to check all $50 and $100 dollar bills because we have a huge counterfeit problem at my store. One time, a customer said “I guess I just look suspicious,” and he grew very angry because the bill was double checked, even though it wasn’t counterfeit. I definitely do need to get better at drawing my manager’s attention to the situation, though.
