What is the deal with these self-checkout machines? I mean, come on! They’ve got us doing their job, scanning the items, bagging them… and for what? To be yelled at by a robotic voice, ‘Unexpected item in the bagging area!’ I didn’t put anything there! I’m just trying to buy a box of cereal and suddenly I’m a suspect in a high-tech grocery theft ring. And then they want a tip. For what? For allowing me to work for free? It’s a whole new level of customer service where the customer *is* the service!
