A lady came into the gift shop today and bought a couple of items. She tried to give me too much money. I tried to explain it to her a couple of times. Finally I asked, "Are you on medication?"
She said she was.
I said, "Well, I'm old, so I think we cancel each other out. Let's do this slowly." Finally she accepted the amount I said was correct, but I could tell she wanted me to take one more nickel.
