Here's one about a stupid customer instead of a stupid cashier. My first job was at a supermarket. Some guy buys stuff and the total is $12.90. The guy hands me a twenty dollar bill and ten cents thinking that this amount will render only paper bills in change. I am confused but don't say anything because I was only 14 and somewhat shy. I ring it up, look at the register, and give him back $7.20 at which point he gets mad and starts bitching about my incompetence to do math.
