Doesn't suprise me.
Once day out in Saudi on the way to the beach or Taif, we had to go past "checkpoint charlie" as we called it (there so that non-muslims didn't accidently head into mecca or medina).
You had to present your passport and igama, no biggie, never had a problem before, but this day there was a tail back because of the american infront.
He was f'ing and blaring about why should he show them his papers, while the police were being as polite as they could (armed with uzi's tho)
In the end, seeing the tail back and having enough with this obnoxious yank, they asked him to pull off the road.
We were up next, so mum made sure we all had our passports and dad's igama.
As they were being checked dad commented that it looked like they had a spot of bother, refering to the yank
"There's always one sir" the guard replied, and with a smile waved us on.
From then on, whenever he saw us, he'd always say hello and see how we were
So the moral of this story is, if you need to get through a security check, it's better to be polite and reasonable than obnoxious (just look at that advert on telly at the mo where the guy has all the practical joke stuff, and in the end gets the rubber glove treatment for it!)
