As someone living in the Nordics my experience already with central Europeans and especially so Americans is that these cultures are already much more high context than the Nordics. I guess up here we're all borderline autistic?
Even UK vs Netherlands is a significant difference in how things work in business deals and that's just a 45 min flight. Unspoken expectations are different on how the other side is supposed to behave.
Denmark is a bit better, maybe because they drink more ? Dunno.
Where do you get that notion? My education (and some googling to refresh my memory) has Norwegian, Swedish and Danish classed as "North Germanic" according to comparative linguistics. That is one subset of the West Germanic languages which most of northern Europe speaks.
Maybe the overall consumption is higher in Germany, but in Denmark everyone is out drinking much more than in Germany.
