I am in the USA but my grocery store trips are not at all like you describe. I walk to the grocery store, collect groceries in a single basket and have them loaded into one or two bags which I walk home with. I do this 1 to 3 times a week. No matter the quantity of groceries, a professional can ring it up faster than I can. > Moreover, sometimes the bagging had been historically done by paid staff, so people weren’t used to doing it themselves Sometimes, but usually there is something like a 1:5 ratio (or lower) of baggers to cashiers so bagging your own while the cashier rings you up has always been common. The way I see it, bagging isn't really a real job, usually the store hires mentally disabled people to do it as a sort of charity to the community (also the feds pay half of their wages.) Anyway, bagging is easy. I don't have to deal with an obtuse machine to put some stuff in a bag.
