I was delighted to see an obnoxious self-important Frenchman removed by the Bundesgrenzschutz Polizei from a Lufthansa flight at FRA. He was told twice by crew to stop using his 'phone after the doors were closed as we were taxiing to the runway. He refused.
His parting words as he was 'gently' removed from the aircraft were : "I will never fly wiz ze Lufthansa again."
The cabin director's response, to cheers, was : "That is korrect, Sir. You will be banned."
