It's been like that in most supermarkets I went in the last 5 years. I don't really see the point of amazon's version. And from what I read it doesn't even work yet. https://arstechnica.com/information-technology/2020/02/amazo...

I'd be really impressed if any large supermarket chain (outside of the US) would be ok to be so tightly coupled to amazon for virtually no benefits compared to self checkout. It's like a lot of what SV is pumping out, half assed solution to non existing problems.

> In Poland most shops allows you to scan and pay for products in matter of seconds without any help. No lines, no hassle.

In my part of the US this is common as well, but there's almost always a line to use the scanners that is about the same as the line for the a human checkout clerk. So I almost always opt for the human.
