I was just in Southeast Asia, and they check the cars that enter the airport (under carriage mirrors/passes), security to enter the building, security to enter the terminal, and security to board the airplane. -all involving scanners, metal detectors, and male/female pat downs.
Surprisingly, it was the Americans who complained the most. I had to explain it to them because they were making a ruckus about getting in line, again. One couple asked if they could just follow me, because they were confused about where to go and what to do.
What sucked was that I had to throw away my water each time. And those airports are hot.
