Many of the audience were tourists rather than typical strip club patrons. Many couples, mixed groups, and girl only groups. It was amusing to watch their reactions.
I used to live in Bangkok so I have seen much wilder shows performed by younger and prettier girls so the oddness of the shows is nothing new. For seeing good looking women naked, it is not bad but you can get better in London. However, if you want to see sex on stage and have a chance of being involved in the show then this is the place.
