Are they all like that? Not at all, but the examples that we encounter via the news only help to solidify the stigma.
Fun fact: The Saudi Airlines plane I was on in 2002 was still on the tarmac more than 40 minutes after all passengers boarded. As the passengers became fidgety, the news broke that a prince in the first class wanted pineapples and that the plane was not going to fly before the said pineapple came on board. So basically, the rest of the plane, the travel schedule, were treated like simple nuisances to what appeared to be a "private jet" even if actually it was a national airline. "Petrole! petrole!" airport scene anyone?
