I just visited some expat friends in BKK. They have a fulltime maid and driver and Chevron does all their taxes. Prior to Thailand, they had a posting in Angola. They went from the airplane to the helicopter to the compound and never left the compound. At one point a missile - not live - was launched into the compound. Apparently the compound was deliberately placed on the water so they could evacuate by boat, which is what they did at the time.
