There was a time when if a masked person walked into a supermarket and was seen on camera slipping things into their pockets, a store detective would be sent to the exit faster than you could say unexpected item in the bagging area. If Amazons plan for cashier-free shopping catches on, this will be quite normal.
Just walk out is the slogan of Amazon Fresh. It is displayed on the signs, the bags and the unmanned exit, an invitation that still makes me feel shifty as I leave the supermarket in west London without reaching for my wallet. I think with guilt about my late grandmother, a former Tesco store detective 5ft nothing but they say she could tackle like a lock forward
