Self-checkout. What a concept! The store is so busy, they need *me* to do *their* job. And then the machine starts talking to you! ‘Unexpected item in the bagging area!’ There’s nothing in the bagging area! It’s just air! And then you have to call over the one beleaguered employee who’s overseeing twelve of these temperamental robots. ‘Please wait for assistance.’ I’m already waiting for assistance, from a machine that’s accusing me of shoplifting a ghost item! It’s like they’ve given us just enough rope to hang ourselves with our own groceries. ‘Thank you for shopping with us.’ No, thank *you* for making me your unpaid cashier!
