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.
Many readers are overly sensitive these days. If you use things like a period on the end of your sentences, and don't include emojis, then anything you say will be called out as "hostile" by some people.

Also, I've noticed many people ignore qualifiers in speech. If you use qualifiers thoughtfully, having them ignored by the reader can lead to miscommunication. I think the fact that so many people have used them without thought has led to a blindness for qualifiers. OTH, not including qualifiers can make us sound authoritative and even arrogant to some people.
For instance, in my first sentence, above, I said "Many readers...", and "...things like...", and "...by some people." If you ignore those qualifiers, what I said takes on a very different tone.
Can't win for losing.
