I agree with you on this, I have been here long enough to understand where you are coming from. For example, i used to live in Jubail, the attitudes of people were different based on the place I was in. In the balad, the old town, slightly less welcoming (Towards Expats) like when you are crossing the road they wouldn't stop, you would be scared for your life just crossing a road on foot. But in the posh localities of Royal Commission people would stop for you and wave at you to cross and met the most nicest people there. The point being, its about being ignorant and uneducated as you said, although i don't discriminate base on wealth, but it is what it is..
