I wonder if in areas where this is a serious problem, we'll see stores operating like they did in the Old Days: customers give a list of items to a clerk who collects them for the customer, instead of customers gathering the items themselves.<p>Stores made this change a long time ago because it reduced costs and increased shopper throughput, but it sounds like, at least in some places, those economics may have changed.
You go into any non american country and you will find a security guard at the door checking bags and they have a locker. You dont always need high tech to solve an age old problem.
