(I’m the manager of a pizzeria. I have all my employees keep their hair very short and clean-shaven. This happens when a customer comes up after just having been served her pizza. Everyone working this shift also has black hair.)

Customer: “Excuse me, but there’s a long, blond hair in my pizza!”

(She stares at me as though expecting me to do something. She also has long blond hair.)

Me: “Ma’am, I’m sorry, but that hair didn’t come from us.”

Customer: “But it’s on my pizza! You have to do something!”

Me: “I don’t know what I can do other than to give you directions to the nearest drug store to buy a comb.”
