Once you scan an item, you are required to put it into a bag to be weighed.<quoted text> I know where I shop if you try to go out the door with something not scanned the alarm goes off. The unmanned cash register is the future. Get use to it.
Alarms go off if-
-item isn't placed in bag
-item is placed in bag that hasn't been scanned
-weight of item in bag differs actual weight of product
