What you describe is not at all my experience in Europe (mainly UK and Portugal, plus a bit Germany).

Small tills with not enough room for a big shopping, pushy and badly designed software, the whole "check your age" for alcohol with a single employee handling 20+ self-checkout tills, the thing bitching and moaning if you bring your own bag, different quirks for self-checkout tills in different stores, not taking cash payments and so on, are incredibly common and what's rare is the ones which work smoothly.

I mean, I would love those schemes some people describe (in Scandinavia?) were you basically check things in as you pick them up, but I have yet to see anything like that myself in the countries I lived in during the self-checkout era.

So far all I've seen in Europe are shit cheap implementations which only ever beat the manual checkout in speed if all you have is a handful of things (so, not a weekly shopping) or the store itself purposefully closed pretty much all manual tills and caused huge queues in order to push people to use self-checkout.

PS: By the way, in my experience in Europe, it's always you that pack your own bags, which actually makes the manual checkout even faster since at the same time the cashier is doing the checkout you're doing the bagging, so the whole thing can go twice as fast whilst in a self-checkout it's only one person doing both.
