A simple way to describe the bar scene it's all one big game, you see a bar with flashing lights sexy little Thai girls shouting hey handsome man where you go?, all of a sudden you think all your birthdays have come at once and your brains end up in your dick,
Most of these girls don't get paid to work in the bars, how they make money is by hustling, for every drink you bought her she gets a percentage, if you looked at your bill them drinks would have been double the cost, and if you were to take her out of the bar you would have paid a "Bar Fine", how much I don't know these days.
Then you pay her to spend the night with you, you see how it works? they have a few 1000's baht out of you, the following day it's rinse and repeat,
