That's a long time ago. Unfortunately, Germany has changed quite a bit since that those days.
But in my rather extensive travels as a financial controller for TWA locations overseas, I found that if you are friendly, the people you meet are friendly. If you exhibit an "often-unpleasant mix of rabid, wild-eyed socialist/environmentalists (with the emphasis on "mental"), and unrepentant Nazi sympathisers," they will reciprocate in kind. You spew hate, they find you hateful. Isn't it interesting how attitudes reflect?
