I saw this video. That young lady deserves a medal and promotion. She kept her cool in the most trying of circumstances, and never once gave him the verbal repartee he was so desperate to enter into. WELL DONE MADAME.
As for the 'passenger' ... I think this sort of individual would merit being on the 'no-fly' list on grounds of endangering the blood pressure of anyone he comes into contact with. Disgraceful behaviour (verbal and the act of filming) from that individual. He may be loquacious, but has not read and understood that he signed that he understood and would abide by the Ryanair T&C when buying his ticket ... that he would have to print out his boarding pass to allow him to board and use his paid-for ticket, and that if he did not and the boarding pass had to be printed out at the airport, it would cost him a certain disclosed sum of money.
Should have gone to his local branch of Specsavers ....
What an unpleasant individual and an embarrassment to all other 'passengers'.
