I run into this process every time I visit Poland (mostly because I visit so rarely that I forget) and every time I'm astonished how seriously fucked up it is.
The most annoying part is having to scan a receipt in order to exit the self checkout area.
In the stark contrast to the above self checkout process in Switzerland works so smoothly. Mostly because nobody is subjected to the bullshit described above. There's even an option to grab a scanner, scan everything on the go and just pay at exit.
Do you actually need to share your bookmarks? I found that bookmarks in Firefox and an RSS reader hosted on my nextcloud are enough for personal use.
