And usually they have a dedicated checkout aisle so you don’t have to wait for the Boomers in front of you to pay in pennies or whatever it is they do to snarl a queue up.

Eh. This "Boomer" uses his Apple Watch, usually. I tend to blow through in about five seconds. I usually have the stuff paid for, before the cashier stops ringing them up.

I deliberately use the manned checkout, because I'm human, and I believe in helping out other humans. That seems to be a "quaint anachronism," these days, but it's the way this old fogey was raised.

I know that someday, I won't have a choice (Home Depot only has cashiers for contractors, nowadays, so I'm forced to use the auto-checkout), but, where one is given, I take the human.

Sometimes, I chuckle, as I go through fairly quickly, and see the long line, waiting for the auto-cashiers.

It's obvious that the only benefit comes to the company. If you aren't just getting a candy bar, then the auto-cashier tends to be slower (mainly because I am a lot slower at that stuff, than the cashier).
