Several times, but not recently, Walmart self-checkout machines would reset after I scanned the first item, I dunno why. But I figured I did my part by scanning it, so I didn’t re-scan it, even though I knew it had reset. I could just play dumb, which isn’t hard for me, if anyone asked. No one ever asked, but they upgraded the software, and it stopped doing that.
The employees seem a bit happier as attendants than cashiers, so I guess that’s a good thing. I don’t know how many lost their jobs to the machines, though.
I’ll admit that I’m happier with self-checkout, because I almost never need to wait in line anymore.
