I remember a French Canadian controller, who told the pilot of a US N registered aircraft, that he wasnīt permitted to speak French on the radio(!) (Even though the pilot in question speaks French) because he was not in a F or C registered aircraft.
Shortly thereafter, he asked to proceed "direct Seven Islands." ATC-"The name is Sept Iles!" Pilot-"If I canīt speak French on your frequency, then it is SEVEN ISLANDS! Now, am I cleared or not?!"
"cleared as requested......."
