After reading the Human Trafficking News posted by George in another topic, thought to open up a topic to get your estimates of the Minimum Monthly Income of a Bar girl in Thailand.
To Start with, I think an average Thai Girl between the age of 18-26 must be earning:
From the Bar [Any salary + commisions etc] – 4,000 Bht minimum
From Customers [average of 1,000 Bht per Night and working for 20 days] – 20,000 Bht minimum
Therefore, I guess she must be earning above 25,000 Bht per month minim
