(A teenage boy and girl come up to my till with a recently purchased CD.)

Teenage Boy: “I want to return this CD.”

Me: “Is there a problem?”

Teenage Boy: “No, I just didn’t like it.”

Me: “Well, I’m afraid I can’t give you a refund, but you can exchange it.”

Teenage Boy: “That’s not on. I want to see the manager.”

Manager: “What seems to be the problem?”

Teenage Boy: “I want my money back for this CD and he won’t give it to me.”

Manager: “I’m afraid we can’t give you a refund but you can exchange it for a another CD.”

Teenage Girl: “He doesn’t want another CD. Why would be want another CD when he can just copy them?”
