Pompous and imperious R/T behavior is, in my view, not limited to certain nationalities
The best one in my memory was a German controller's reply to a recalcitrant Delta 'good ol' boy' in FRA one morning
Having tired of them man's repeated requests for direct / lower - and petulant complaints when his requests were not granted - FRA approach finally got fed up and said
"...Delta xxx, if you cannot do as your are told, you will go to Rudesheim and hold until you can..."
Needless to say, nothig further was heard from the DAL skipper that morning.
