(I am on a school trip to a mall to help with pet adoption forms. A customer comes up.)

Customer: “Gimme a f***ing dog!”

Me: “Would you like an adoption form?”

Customer: “I don’t care. I just want a dog! There’s one over there! Gimme it!”

(I look to where he is pointing. A lady is walking a dog.)

Me: “I’m sorry, but that dog doesn’t belong to us.”

Customer: “It’s because I’m [ethnicity that he clearly is not], isn’t it? ”

(At this point, I realize that he is high.)

Me: “Oh, that one is ours. Unfortunately, it is an evil space cow.”

Customer: “Holy s***!” *runs off*
