Been an expat for 40 years, including 10 years in JED. One thing I have learned is that stereotyping people based on their nationality never works. Pretty much all humans are equal. Good apples and bad apples come from every harvest.
Living in Jeddah was fun, the lack of alcohol was not an insurmountable problem, the diving, sailing and golf was pretty good and the social life was most excellent. We had fun and really enjoyed our time and still hold fond memories of KSA and our many Saudi friends.
The nastiness displayed in this thread does not do anyone any favors. Worse still, it makes the profession look pretty low class.
ps... is that old sand golf course (Desert Lakes Golf Club) just north of the airport still there? Please don't tell me its been converted to yet another shopping mall!
