When An Inability To Do Math Meets “Oh, No, The Consequences Of My Actions”

I am ringing up a guy that has two books and a coupon. The books are a paperback and a hardback. The hardback is 40% off but is still more expensive than the paperback, so I apply the coupon to it.

Customer: “What? You need to put the coupon on the paperback because the hardback is already discounted! You’re ripping me off!”

The guy’s wife shows up.

Customer’s Wife: “Honey, just go with it.”

Customer: *To his wife* “No! I am the customer and they have to do what I want!” *To me* “Use the coupon on the paperback!”

I comply and give him his new total.

Customer: “But why is it more expensive now?”

Customer’s Wife: “Because you’re an idiot.”
