Has A Card-Sized Chip On Their Shoulder

(I am processing a return for a customer. Though we have a chip reader, returns still have to be processed by sliding the card.)

Me: “All right, the machine down there will have you slide your card for this return.”

Customer: *inserts their card*

Me: “It’ll actually have you slide instead of using the chip, since it’s a return.”

Customer: “But my card has a chip!”

Me: “Yes, but for this one, you’ll need to slide.”

Customer: “It’s inserted! I don’t know what you want me to do!”

Me: “The return can’t process with the chip. It can only be processed by sliding the magnetic strip on your card.”

Customer: “I DON’T KNOW WHAT YOU’RE SAYING! MY CARD HAS A CHIP!”
