We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
Our local CVS has one self-check-out station. It works pretty well most of the time. It's actually a lot easier than checking out at the normal counter; Those Plexiglas barriers make it almost impossible to pass a large box of something to the checkout person. A few times I've had the self-check machine lock up on me, requiring an employee to unlock it. Sign of the times, I guess...
The checkout kiosks are a big money saver for retailers, but the time-wasting elements of it go straight to the consumer. It's the equivalent of being stuck on the telephone wasting 15 minutes of your time navigating voice menus before you're placed on a 20-minute hold waiting for the Live Human - and being forced to listen to ads the whole damn time.
They'll station one worker to manage a dozen kiosks, and inevitably you're waiting for that person to become available to unlock your kiosk because you're buying forbidden fruit, as noted above. Kroger gotten slightly better - the worker now just does it through their phone.
Which is exactly why Walmart is doing it- one of my children works for them and says straight out cashiers are hard to find.
It's why fast food retailers offer all kinds of goodies and rewards- if you use their app to order. Order at the counter- less rewards. If any. App ordering reduces their labor costs. I see the eventual demise of kiosk ordering- apps cost even less.
As for self checkout- 90%+ of the time it's faster. But remember the "5 item or less express lane"? All retailers need that for the self checkout area.
Self-check works great for prepackaged stuff with a legible bar code; I use it at Home Depot all the time. But I buy lots of fresh produce at the grocery store, and I'm not about to stab my way through 6 layers of menus to find the price for serrano peppers, and then again for a half-pound of mushrooms. Besides, cashiers gotta eat, too.
