Sensual activities and you wont regret.The only negative stuff is the Burmese girls have the intention to go home between 6 and 7 am, that's nonsense, but they do this because they guess nobody will see them. So when you like tell them and make sure they understand the party is not over before lunch time.
If you like some of the ladies don't be shy to take the first step which means buy the some flower garlands when they move up and down the catwalk they will come to your table and lets see what happen. At other places they have a "mama san' be aware that you need to straighten out things with her.
This are usually elder women who have been in the business before but nobody is interested in them anymore so they are managing the girls. They usually take about 50% of what you pay the girls better negotiate with here before leaving the bar.
