Arghhh! Who designed the self-check-out machines that have proliferated of late?
Regardless of the store, the self-checkout machines have exactly the same design so somebody, somewhere, is making a lot of money selling them.
I can only assume the manufacturer has a rock-solid patent that is keeping rivals from competing and protects their sordid little monopoly. How else could they get away with failing to fix gaping defects in the user interface that have persisted since they first appeared several years ago?
"Item removed from bagging area"
... yes. I know. The bag was full.
"Please return item to the bagging area"
... WHY?!!! WHY SHOULD I?????
"Unexpected item in the bagging area"
... YOU JUST TOLD ME TO!!!!! I want to cry now :-(
Useless, useless, stupid, stupid machines.
I see I'm not the only one who hates them... (the date on that post also shows that the user interface stupidity has persisted for at least a year.)
