Only spend eight years working Retail in a Big Box Store with these Self Serv Theft Machines. Company policy as to theft amount prevented anyone assigned to the Self Check or else where for that matter,from confronting and holding the Perp until Police could be called.
Watched people do the no scan trick time and time again. Most times when caught they will make some silly ass excuse why they put the item in the bag without scanning. And scan the item and apologize. BTW,there is always a video tape that does not lie. But,we had our regulars of a certain Religious Group who prided themselves on trying not to get caught. When they touched that .38 in their waist band,there is no friggin way I was about to push the issue.
So if this person was caught skipping with a Hundred bucks worth of Groceries,well Kiddies this was not her first Rodeo. She has worked the system to the tune of thousands.
Retail fact when scanner self Check outs are used. Store Inventory Shrink expands by 2% and normal excepted shrink is just under 2%. And as a result of Self Check,all prices are raised to cover this extra 2%.
