Today I got a bit sarcastic with a customer who was a persistent stiffer.
On a $22.92 transaction she gave me $23.00 and told me to keep the change. Since I fully expected to be stiffed by this customer I had the eight cents ready for making change. I gave the eight cents to her and said, "here, you keep this, you obviously need it more than I do."
She thanked me for the change.
She apparently didn't get it. She's probably a Democrat.
