Sounds familiar, lol. I used to work at Wal-Mart till last week, Quit, My point being that things like that happens all the time. For example when i was cashiering at the self checkout, I would catch people scanning a home theater in box, on my computer screen it would pop up 99 Cents...they would look up at me and hope i didnt notice. So just before they finished and were to pay, i would just walk up and void out there purchase and take tehre stuf and say they couldnt buy it here. They would have this look of "BUt why, i didn't do nothing wrong" then Stupidly ask, Why not, I'm going to speak with teh store manager. So i lift up up the box and peel a clearance christamas item sticker they put on the over the barcode area. He proceeded to say he didnt put that there, it must have been there already. When i came into work they were just putting those on the shelves as our new add week item, it was on sale for $249.97. I asked him if he wanted to talk to teh store manager again, he told me to "EF OFF" and left. An Hour later he can in and tried it again while i was at a regular register, by this time i told security about him, so they knew of his doings, he scanend it, payed 99 cents, and got stopped by the cops and security. He had apparently been using our self scans for this kind of activity for a few months now, and had his family doing it too...Took our so called Asset protection (Security) long enough. So by these findings, our store manager put closed permanatly signs on teh self check outs and took out teh receipt printers (dunno why, but store managers always have to do stupid unnecesary things to feel overly important). On the topic of hom depot, i went online last night at about 9pm, applied for home depot, and just got a call about 1.5 hours ago for an interview at noon today. I have no specialty skills or anything, only that i have worked retail for a year.
Interesting I was curious if people tried to cheat the self checkout process. I myself make sure everything is rung up correctly and included on the self check because mistakes there are direct stealing and police action likely. When a cashier screws it up then it is more indirect stealing. Then if someone is putting a new price tag on the item that is again very illegal and merit for a police call.
I would think that overall though the self checkout produces less loss to the store than the regular checkout.
Human cashiers produce many more mistakes than the Self-Checks and I think many people don't correct the human cashiers mistakes.
