Our friend Grethe is a Dane. For "many thanks," she writes "1000 TAK."
Takes me back to the 70s, when I used to ride the red double-decker London bus (#68, Camden Town to Aldwych). The conductor would punch your ticket and say "tak."
The conductors were "Pakistani" (or so I was told; they were brown-skinned, apparently Asian). But the story was that they had taken the jobs in succession to North Britons--i.e., descendants of the Danish invasions.
