How about when they scoff at your having brought re-usable bags, slightly demanding of them to do something different? Or when they pack your goods in a way that damages them? Or puts colds next to warm, or highly heat conductive items? Or when they're clearly sick, and likely spreading that illness to everyone that comes through that lane? Or when they're at the end of their shift, hate their job, and give you that lovely dead-eyed stare that just makes you feel warm and fuzzy when you try to make small talk?

How about when they reek of cigarettes? Or when they make a mistake (and they do) and all the people behind you start eyeballing you and the cashier, clearly upset at the delay? How about when they ring up produce incorrectly, or double count items, overcharging you? How about when something comes up wrong, and then they argue with you, because they're stressed with a queue to process?

Human cashiers being objectively better in every way than self-service automated lanes is not correct, especially as you sample more and more cashiers. SOME cashiers are better. Many aren't.
