dear evilspawnsss and no-go bros..
come to think of it, 20K cut for the cabbie's is actually very very reasonable already because the poor chap brought us to about 5 joints before we decided on our gals, which happened to be at last joint we visited. Even if the cabbie didn't ask for the commission, I'd still give him about 20K as comms as he's really patient and helpful bringing us around. They still need to make a living mah hor?

From this experience, I'd say the 'market rate' would still be between 20-30K for the cabbie's cut.
I rated the cabbie an overall of 8/10 for his services.
Anyway bros, if you guys do intend to visit BT again in the near future and if I can be of any help in any way, do PM me ya? I'd give you both my help as much as i can. I'd probably visit BT again sometimes in either July or August, and very likely I'll stay in Hotel Utama.. the hotel front office recepts (chinese) quite chio man! *evil thoughts* heeheeheehee...
cheers bros!
