I can’t think of the last time I went through a self checkout without having to wait for an employee. Sure, a lot of the time it’s just because I’m buying a bottle of wine or whatever, but, like, that’s still a problem.
It’s also super terrible security-wise, because it incentivizes employees to make their account credentials whatever is quickest to type in on the kiosk that seems to have less processing power than my cellphone. I usually look away out of politeness, but I’ve glanced at their codes a few times. Saw one that was literally 0000. Another that was just 1, because apparently they don’t even necessarily have any password requirements lol
