That’s what Amazon CEO Jeff Bezos appears to be thinking, as his Seattle-based web giant has contemplated a two-story, automated grocery store in which a staff of robots on the floor upstairs grabs and bags items for shoppers below. The ground level of the futuristic prototype – a supermarket-sized version of its recently unveiled “Amazon Go” convenience store , with a bigger layout that could span anywhere between 10,000 and 40,000 square feet – would be devoted to goods that shoppers typically like to touch, sources briefed on the plans told The Post.
