Well to be fair I once got a flight back from Paris with some 40 ish orthodox Jews, to say it was the flight from hell for the rest of the passengers and crew would be a understatement.
They were rude arrogant and downright nasty to the crew,they kids running up and down the aisle, them getting up walking up down nodding and praying.
As soon as the wheels touched they all got up chucked everyones luggage out of the overhead lockers to get theirs and stood by the exits, fair play to the captain he held on the taxi in until everyone sat down and threatened them with the police for endangering the aircraft.
Some of the comments coming off were priceless and very racist.
The trouble with posting this is that you are now open to being called anti-zionist, nazi, holocaust denyer etc etc etc. Whereas, in reality, all you have done is provided anectodal evidence of a group of unpleasant and anticsocial, selfish people, who happen to be jews. Anyone who has holidayed could provide similar experiences of different races and cultures, so it isn't uniquely a property of one sect of religious people.
