I am a regular in a very popular bar in LK Metro and I never have paid lady drink prices...in this particular bar they are 140 baht...being a regular quite a few of the girls come for a chat and they know that if I tell them do they want to have a Beer with me it is Tamada...same price as mine...OK now understand?
They have a table outside that usually has... among other drinks...a bottle of Sangsom for the girls whack between themselves...I have on several occasions bought a bottle from 7/11 for them to share....but buy lady drinks no.... that's not me...I leave that to the tourists
