Invisible Incentive

(There were a series of compilation albums on release called “Air Guitar Hero” which had a very tongue-in-cheek advertisement. I have just sold a copy to a customer who returns to the store ten minutes later.)

Me: “Are you okay there?”

Customer: “Well, I didn’t get my free air guitar with this CD.”

Me: “Excuse me? I’m not sure what you mean.”

Customer: “This CD, it’s supposed to come with a free air guitar.”

Me: “…”

Customer: “On the advertisement, the one on TV. It says comes with free air guitar!”

Me: “Um, that’s a joke they made on the advertisement.”

Customer: “But it says on the advertisement I get a free air guitar with this album!”
