Also, you don't have self checkout "stores" here. Essentially every supermarket has a self checkout section. You can just make your judgement call in there on the fly. It's pretty much always faster though even if someone has a decent sized load due to the shared queue system.
I think if someone brought 50 items to self-checkout area, they would get knifed in the back.
There are usually at least 6 terminals, so if you have a incompetent idiot on one of them, it doesn't make too much of a difference.
About 90% of the time, there's no line.
The ones I will never use are those which have a voice you can't turn off. Having to listen to those as I queue nearby, all I want for xmas is a HIMARS.
I am picturing the hand model from zoolander, with the glass protection orbs, making someone else do absolutely everything for them.
The worker scanning and bagging my groceries is a service that makes my shopping experience more pleasant and less taxing on me. I'm not giving that up in exchange for nothing.
It's the exact same amount of robot, just more dumbed down when it's customer facing.
