It's always the bagging thing that fails for me. I'm not the smartest person in the world but I can scan an item and place it in the bagging area. It's kinda out of my hands at that point. Be it calibration or incorrect data sometimes it won't recognize and after a couple attempts locks and some underpaid person has to come roll their eyes at me and swipe a card to let it go through.

I've probably just been unlucky and gave up 10yrs ago on that.

No they don't train cashiers beyond what button to press. Produce is interesting. It's been a while (love curbside service) since I've been in a grocery store but ours has tags on produce you show to a scale and it weighs it and prints out a sticker with a barcode.

And I just realized how abusable that is. I'm going shopping tomorrow!

Oh what's the 4011 thing? Doesn't ring a bell.
