Will Tesco shoppers freak out at six-foot tall RFID robots?

As Tesco clothing shoppers rifle through the chain's apparel assortment, they'll be sharing the aisles with six-foot-tall RFID robots, rolling up and down scanning clothing tags for inventory. (Personally, I think a Texas approach — where the robots would be equipped with automatic weapons and paid for out of the loss prevention budget — would be more interesting.).
