Thankfully it seems both cashiers and baggers are better trained than they used to be at least at the larger chains. I don't have either of these issues at supermarkets.

That doesn't mean they won't be lazy or lack hustle though.

Sometimes I catch incorrect prices or the cashier keying in the wrong vegetable at checkout, but you can also read your receipt later and ask for a refund. I’ve never had a grocery store quibble when I said I was mischarged or an item was bad.

Why does this kind of thing only happen in the US?

wait employees bagging your items is a real thing in the US? why? what's this american obsession with having shittily paid people do everything for them?
