Major international airport somewhere in Germany, usual chatter on the clearance frequency.
German pilot pipes up requesting clearance in German 'Lufthansa yak yak yak bratwurst etc'
Controller replies (in English mit accent) stating that transmissions must be made in English.
Pilot replies ' I am a German pilot, sat in a German owned plane, flying for a German airline, at a German airport, why can't I speak German?'
English public school accent comes on frequency 'Because we won'
God bless.
