A Hundred Bucks Is All It Takes To Learn Telepathy

(A lady comes in to buy ink for her printer. She buys a combo pack that has both the black ink and tri-color cartridge, and also gets one extra tri-color cartridge by itself. She then comes up to check out.)

Customer: *hands me a $15-off-$75 coupon*

Me: “Oh, right now your total is $63; did you want to get anything else?”

Customer: “I guess. Get me another combo pack.”

(I go get and another combo pack and ring it up.)

Me: “Okay, now your total is $107 before the coupon.”

Customer: “What? Why so much?”

Me: “Well, each combo pack was $42, and the extra color cartridge is $23.”

Customer: “Wait, why did you scan that extra color cartridge?!”

Me: “Oh, well, you brought it up with you. Did you not want it?”

Customer: “No! Why did you scan it?! A hundred dollars is way too much; you should have known I didn’t want it.”

Me: “Um… All right. I’ll remove it.”

(I remove the extra cartridge and apply the coupon.)

Me: “Your total is $63 now.”

Customer: “See, now isn’t that better and easier when it’s done right?”

Me: “Yep.”
