I was using the self checkout the other day and scanned some item and put it in my bag. A store employee came over and told me it didn't scan. Hmmm? I looked at the screen and yes, the item was listed on there. She checked some handheld she was using and it wasn't showing up on _her_ list. So she could somehow see what I was scanning and apparently was watching to make sure I wasn't stealing anything? It was kindof odd.
