Welcome to Checkout-Free Retail. Don’t Mind All the Cameras

The shop has no sign. Or rather, the sign is obscured by some kind of bunting. The glass doors are papered over. You gotta know what's back there, like a speakeasy. Venturing to open the door, I find I still can't get inside. Between me and a cramped 180 square feet or so of convenience store-like shelves—yogurts, bags of exotically-flavored freeze-dried peas, refrigerators full of juice, and pre-packaged sandwiches—is a turnstile. It is a shop. I will shop. There's a reader on the right.
