That is only the case at short sighted stores that assume all customers are out to steal. The units themselves can be quite good - Wegmans has machines as quick as the ones I used to use when i worked as a cashier at a grocery store. As near as I can tell the main thing is the Wegmans self-checkouts don't weigh the items you put in the bags.
