A few years ago, I had been out drinking with a friend who flies for EK at the Irish Village in Garhoud and were stumbling our way back to her apartment just across the old parking lot when we were stopped by a bored UAE policeman in the mood to cause trouble. She is technically Muslim so was smart enough to claim (in Arabic) that she didn't have any ID with her. I was very lucky that I had an old Saudi visa in my passport that gave my religion as Christian (I'm an outstanding Christian - I go to church and I stand outside!), so the police officer gave us a stern warning in Arabic and let us go. I've been a lot more careful since not to step outside of a hotel when even mildly inebriated.
