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.
Not really, if you get a "yes" in the Netherlands, Nordics, Germany or Poland it does mean, simply, yes.
The consequence of which is that actually getting a "yes" takes a lot of work.
I don't dare speak for other countries, no experience there.
