Customer: “Oh, I needed help putting in this cat food, and the young man put in the wrong brand!”

Me: “Okay, let’s go over there and get the right one.”

(We walk over, and she looks at about five different bags of cat food, then goes to a bag of litter.)

Customer: “I think it was this one I wanted.”

Me: “Wait, did you want cat food or litter?”

Customer: “What’s the difference?”
