>> The Dutch can be horribly rude and argumentative...

As a Russian, so can I. It can be a useful trait under circumstances, but I generally try to keep it in control.

If I get an idea to work in Europe again, I'll pay closer attention to the Dutch opportunities. It's important for the people to "click" on a cross-cultural level in order to work well as a team, and I'm afraid I didn't click nearly enough back in Germany.

Anyway, no culture is perfect. We're supposed to learn from each other and work on our bad sides as recognized in others and by others.
