I heard from one cabbie that there are indeed some deligates looking for chick in Geylang. I think it is one of the earlier ones when the Mercedes cab just started. They were used to bring deligates around. Some from the less wealthy nations did go Geylang to look for fun using the taxi.
Its on company's account and its legal here so why not?
I used to know a guy working for UN who used to bring delegates to Joo Chiat Bars for happy hours......
