I don't know.. i was in Kuwait couple of weeks, i got to know 2 kuwaitis.. I was in Dubai one day (without my hub), I got to know 2 emiratis.. in qatar I know some qataris, both ladies and men.. I used to work with mostly qataris in my previous company, and now we have couple of qataris employed with our company..all of them are very pleasant and friendly.. Especially I liked one lady from my previous Job. She was so much friendly and positive! Her unique laughter could relieve any stress in 2 seconds..
I think it also depends on your own attitude..
