ugh. our self check machines are like the most retarded things ever. The regularly freak out when you put the item YOU JUST SCANNED into the bagging area. If you have a bag it does this particularly. No amount of "add my bag" fixes it. It just freaks out like: OMG WHAT IS THIS WHA TIS GOING OMG.
And then one got stuck in a loop when someone scanned a $0.50 pack of gum and put down on the thing today. No amount of "i don't want to bag this item" made the fucking thing go away. So I had to restart the whole damned machine.
ETA: And our POS system will not let you swipe your card if it has a chip. So if your chip is in some way damaged you're basically fucked. I had two people today trying to use the self checks without the same of thirty minutes, with broken chips. I finally managed to get one working, but the other had had to use a completely different card because the fucking system wouldn't let him swipe despite his chip being defective.
(Yes, yes, I know go get it fixed if it doesn't work but he should /still be able to swipe!/ augh!!)
