This story reminded me of my experiences working in a bar (in the UK, chip-and-pin was a thing but contactless was only just rolling out) It was mainly a student bar so basically every card was a debit card... I occasionally would come across declined card receipts from the machine for some 6 figure amount that had been attempted to charge. Was concerned at first but what had happened was clearly the staff member had forgotten to press enter after typing in the amount, the customer still saw the amount - put in their pin, enter, now it says type pin, try again, then panic when their bank declines it. Luckily the only bad thing that would come out of this is that they should go to the ATM and change the pin, after running the transaction again properly.
