In the 18 months run-up to the Asian games the Sherazad used to be awash with Chinese hookers. They could be recognised by the converstaional opener "I give you nice time 500 riyals yes?" When the Games were over they seemed to clear them out but I suspect the reputation has just lingered since then, though now and again there is a likely suspect.

It can be hard to tell, for - as a comic there once remarked - there is one question that there is no way of asking a girl without risking offence: "Excuse me, but just to be clear, are you a prostitute or do you just look like one?".
