I hate them because I have a toddler and making sure they don't run off, move things from the scale, grab candy from the very child friendly height displays, all while trying to scan and bag my groceries.

At staff checkouts we load on conveyor belt together. I can keep control of my child. And then we leave.

I hate self serve. Staffed checkouts are much more relaxed for me. I did like self serve better before kids though.

I hate using them most of the time because it's a bullshit hassle for me to unload and scan and bag all of my groceries, when there used to be an employee to do that for me. I don't work for the fucking store, their employees do, so they should do that work and get paid for it. The stores where I shop have gradually scaled back real cashiers for machines to the point that it's more inconvenient for all.

The only time I like using the self checkout is when I'm buying rubbers and sex lube. The cashiers always laugh or make a face when I put the Magnum condoms on the belt.
