When was Germany supposed to have had baggers according to the book?

When Aldi came to Denmark and didn't redesign the checkout for not having baggers.

Germany never had baggers. In fact, to me as a German, the job of a bagger appears about as nonsensical as that of a telephone sanitizer.

Walmart had baggers for the short time they were operating here.

Did they? I remember shopping at Walmart around 2000, but I don't recall seeing baggers there.

What are baggers? People standing after the checkout that put stuff into bags for you? If so, that sounds quite unusual, unnecessary, and even annoying to me.

Yes. Here in Australia the cashiers usually do it for you, into rather flimsy single-use plastic bags.

Seems a bit foreign to my German soul, too.
