It's a totally different scene and culture here. When I was out in Asia permanently, guys from ISG would post to see who was looking for a night out mongering or a daytime session of mall strolling.
The mongering consists of visiting bars/clubs so although it wouldn't be strange to go alone, best to make a night of it with another expat to survey the treasures on display. This could involve visiting 3 or 4 establishments before you find what you are looking for. Once you have your chosen lady for the evening, you can socialise or disappear back to your diggs. The girl is paid once you decide she can leave and can pay based on performance.
Mall walking is as it says on the tin. Girls over there may hang out during the day looking for meal ticket. You just have to spot who's playing the game whilst ensuring security aren't tuned in. Once you've a successful hit, an invitation for food, cheap nearby hotel and a couple hundred thousand (£10) before being bungled into a taxi.
Sorry to go off on one but my experiences in this area is far different to the scene here. This is possibly why I've hot no issues with meeting up with a mate to head for a massage or more.
