Like everywhere you get unpleasant fellows on both ends. However, I have personally found most of the Saudi ATC's over the years to be fairly pleasant and polite. In fact I recently had one of the most friendly and polite ATC's I have ever heard when entering Jeddah airspace coming from the South. We were actually sorry to leave his airspace!
Now the Indian ATC's as someone mentioned..........could start a new thread on those characters!
