Brains Over Brawn, Part 2

(I am working an average rush hour at a large grocery store when I approach the end of an elderly woman’s order.)

Me: “Okay, this will be $46.48.”

Customer: *starts hitting card reader with signature pen* “Your machine isn’t working!”

Me: “Ma’am, you need to swipe your card before you can sign.”

Customer: *continues to hit card reader with pen* “Your g**d*** machine isn’t working!”

Me: “Ma’am, please stop hitting the machine. You need to swipe your card.”

Customer: *throws pen at me* “Your machine’s broken!”

Me: “It isn’t broken. You just haven’t swiped your card yet.”

Customer: “Your machine’s broken! See?!”

(When she flips the card reader around, it is indeed broken—by her, of course.)
