(This takes place when people still primarily use VCRs. A customer comes in, rents three tapes, and leaves. He comes back in the store, very upset.)

Customer: “You rented me the wrong size tapes!” *slams three video boxes onto the counter*

Me: “Sir, we only carry VHS tapes. Did you get a BetaMax?”

Customer: “I know what a VHS is! But, these don’t fit!”

Me: “Okay, let me check them.”

Customer: “Go ahead, try to put them in your machine!”

(I take the first box, open it, and begin to insert it into the front of the VCR.)

Customer: “Oh, you mean you have to take them out of the box first?”
