Hand held scanner at the grocery store!
I went to the grocery store yesterday and they now have the hand-held scanners to carry around the store with you. You scan your item and put it directly in your shopping bag in the cart. At the self-service checkout, you scan an exit bar code, pay, and go. The items don't have to be lifted onto the belt.
I found myself distracted by the scanning process and did a lot of backtracking in the store. And I seemed to be the only person using the scanner. It looks like a shoplifter's dream - I almost bagged an item without scanning.
