(The bookstore I work in offers complimentary gift wrapping for customers. It’s a steady night at the bookstore and a woman approaches my register.)

Me: “Hi, how are you?”

Customer: “I need to get something gift wrapped.”

Me: “Sure, do you have the receipt for it?”

Customer: “No, I didn’t buy it here. I bought this from another store.”

(She takes out box of perfume.)

Me: “I’m sorry, but I can’t wrap something you bought from another store. You’re going to have to buy your own gift wrapping paper and wrap it yourself.”

(Ten minutes later, the woman returns to my register with wrapping paper in hand.)

Customer: “Okay. Now can you TEACH me how to wrap it?”
