Bro Soopafly,
I won't say I have black magic, but I use the law of diminishing returns and the principle of supply and demand in my favour.

in sillypore, some brudders throw money at coyotes in the Thai discos. Coyotes in SG have the control over which table gives them the most flowers and LDs, so us bros with shallow pockets can't dish them banners or LDs. But in LOS, we have the control, many girls and all wanting to earn money.
However, I noticed that working girls or ladyboys are individuals seeking acceptance from their peers as many of them are from rural backgrounds. I watched a documentary shared by a bro in the links page about ladyboys, it was mentioned that money and status means everything in Thailand. I believe around the world is the same. Someone can be the f-ugliest person but with good family status, outsiders will still show respect.
Using this information to my advantage, I would enter an AGG and sit down near the door and the stage. Never going in too deep into the bar. 2 reasons, #1 if the multiple batches of girls not for my liking, easier to leave. #2 Fishing random girls who walk aroun the bar and outside would tend to stop and say hi.
Application of demand and supply in reason #2
Since girls keep walking pass the front or the door and rotating round on the stages, you will get many eye contacts. Smilin to show interest but when they ask to join u with the (gesture, pointing at you then themselves followed by a OK sign) I'll shake my head.
I'll normally go to bars after midnight. I understand some bros would say the "cream of the crop" is taken and I agree with them. But "free from the crop" needs some loving too.
After the multiple head shakes, they would still come over to your seat, wanting to be barfine, due to the timings I go to the bar, waitresses and mamasans are breathing down your neck to barfine the ladies. You have to remain strong willed not to pay. I would simply say I'm tired no fuck tonight. Just wanna drink and see pretty ladies. Telling the girl right infront of me, "yes, you pretty, you suay mak".
The fishing games beings......
