It depends on a machine and a store. At least in Poland, I’ve seen a bunch of terrible ones, but most of them are pretty decent. In my local Leroy Merlin, there are 10 machines, all of them busy during rush hours, and just one person staffing them. Plus a security guard that would be there anyway. Similar in large Carrefours. With smaller grocery stores the self checkouts added an extra place for self checkout, with keeping staff unchanged. Rossman (european cvs/wallgreens) regularly has fully unstaffed self checkouts. The guard was always there usually by the door anyway. On top of that we have Żabka Nano - a fully automated store. I haven’t been there yet, but from what my friends told me, it sometimes is fully unstaffed (unlike it’s Amazon counterpart which seemed to have more staff than traditional stores of similar size). Then with Uniqlo UK that I visited it was pure magic - rfid on clothes, you just put a bag in a checkout area, tap your card and you’re ready to go. There is still one or two people of staff, but before they would need 5-10 to handle the same amount of traffic. The main issue with self-checkout in supermarkets seems to be products that can’t have barcodes - bread, buns, etc. Better vision AI that we’ve seen recently should handle that case soon. - before me boycotting Leroy Merlin - they moved out of Ukraine, but stayed in Russia after the war began
