(On the overnight shift we are not allowed to open the safe. To make sure we have cash in our drawers, we put signs on all our debit card readers saying ‘No Cashback’.)

Me: “Your total comes to $15.97.”

Customer: “So, I’m not going to get my change back?”

Me: “Yes. Yes you are.”

Customer: “Oh, okay. Good.”
