When I arrived to Dubai for the first time, the management of my company ask me to be careful with my behavior because we were in a muslim country and then told me an urban legend that years later I heard again from a different source, so it might be true.
In our company we frequently have french guys coming. One of them had some drinks in a hotel, met a girl, went to the hotel room, they got busy, when she was about to leave the room, he notice that some money was missing from his wallet.
For him the most common thing to do was to call the police to complain.
short story, they told me that he end in jail for a couple of months, fined and lashed.
