When I was about 8, my Dad gave me a dollar and I went over to a counter that was selling hot dogs, cotton candy, ice cream and other "goodies." I ordered a vanilla ice cream cone.
The guy behind the counter asked me: Do you want mustard on your ice cream, little girl?
I started to cry and ran to my Dad and told him what the guy said. My Dad replied: You should have told him, no thanks, I just got a haircut!
