The chain "Meijer" has this option. It slows down the process while you're actually finding the items in the store, but drastically speeds up the checkout process as the cashier only has to "verify" between 3-7 items. They just randomly grab them from whatever is on top of the cart, scan them, and away you go!

Walmart now has this. The first time I used it I was asked to allow a random screening of 3-7 items, but since then I have not had to deal with that. Just scan and go.
