Ya see, I’m split on it. On one hand, when I was a kid and I saw videos with old-timey american big shops - be it toys, department or something - all big, open, welcoming with everyone smiling and that super fun and nice atmosphere I was sooo sad I couldn’t experience that.
On the other hand, self checkout cuts roughly 5-10 minutes of time each time I go to the shop, and as I pretty much speedrun what I need and beeline it to checkout, that means I am spending 10 minutes max at any shop with these. It’s so damn convienient I started ignoring shops without it.
But then…I live in european country, and there the only thing preventing theft is a scale inbuilt into self checkout, sometimes coupled with receipt barcode scanner at the exit. Most bigger, and I mean bigger, shops with these have whole one employee per 6-8 of self-checkouts, pretty much there to help in case of approving your age or dealing with more problematic products, like clothing, rarely with something too light for scale to detect.
