At this point I find the errors are pretty rare and much prefer self-checkout, mainly because it’s faster, and as you put it, I often don’t care for peopling.

I quite like self checkout, because I am quite a bit faster at scanning my own stuff, than the old as shit people in front of me, who need to find exact cash, and need to read the entire receipt before moving, so they can complain to the cashier that they paid €0,1 too much for their carrots. Even better is mobile checkout though, so I can just scan whatever I need on my way through the shop and pay while walking out.
