I would hope people don't read this thread and think ALL Qataris would behave in this way.
But your diplomatic post made me think of another, related issue: natural consequences.

(Allow me a moment to step up on my soapbox on this particular issue in this culture...) Many people here don't enjoy the chance to experience the natural consequences of their actions -- because other well-intentioned individuals step in to save them from their fate.

In so doing, they are depriving that person of a valuable lesson, causing them to repeat the same mistakes, again and again.

I would venture that if this gentleman was detained even briefly at the airport upon his arrival because of his in-flight outburst, he would think twice before behaving in such a fashion again.
