Congratulations to Roche Bros for swapping the order of the YES/NO prompt on their cash register card reader.
The display used to ask if you approved the final payment amount, and displayed:
YES? NO?
But the physical buttons on the device are in the opposite order:
NO YES
Now all is right with the world and the display now reads:
NO? YES?
Thank you Roche Bros for making this small part of my world a little bit brighter.
