You might find it surprising (she said tongue in cheek) that my experience has been that all of the Nationals I have met have different types of personality traits and characters. Who knew - I thought they were all cut from the same mold - I mean afterall they all look alike right? (rolling eyes at my generalization)

Seriously though - there are many Qataris at my place of employment. Of course I have not met all of them but the ones I have met have been very nice and as Abu said, incredibly polite. The individual Qataris that I work closely with are courteous, helpful and a couple have quite the wicked sense of humor just like our own Diamond Girl. )

Maybe, singleguy, the arrogance and unfriendly attitude is a projection of your own behavior.
