They come across to me like that.They are wary sort of people as if they think your going to pickpocket them.Once the conversation gets going they come out of there shell.
You summed that up pretty well.Like the Turk one and you got that spot on.They are the most nicest people you can meet when money is being exchanged.
The French are my least like nation.I find them rude,horrible people.
You got the Germans spot on.I quite like them.
No comment on Russians?
