(I had just finished a customer’s transaction, and was gathering up the change.)

Me: “All right, your change is ****.”

Customer: “Wait…I don’t like people touching my money…is there any way I can just take it out of the drawer myself?”

Me: “…um, no.”

Customer: “But what am I supposed to do? I don’t want you to contaminate it with germs!”

Me: “…get a debit card?”

(He leaves with his contaminated money, quite annoyed.)
