Today I stopped by the local Giant Food to buy some of the fat free gravy that I like.  I was surprised that they had a new technology going there where you can scan your own groceries and bag them when you take them off of the shelf, and then when you are finished shopping you go to the cash register and plug it into a holder, it downloads into the cash register what you are buying, you swipe your credit card, sign the signature panel and you are done!  Sure did cut down on wait time at the cash register!  I think I like that!
