Personally - a go-go joint does absolutely nothing for me. Of course, Tongs doesn't do much for me either. I will say nothing else on that point though as I do have a stellar reputation to uphold.
Tongs doesn't really get moving until about 11:00 - which is long after the Complex has closed down for the night. Of course, lately, Tongs has been dead even at midnight and closing time. Ultimately then, Tongs is out of the equation. Yes - some strange things go on there - however it is not necessarily employees doing the "shows" and the girls are for the most part, wearing a lot more clothes than those at Scorpion.
As I understand it - the regular police have already been to Scoprion and given them a warning for hiring / using underage girls. Hence, they are technically on thin ice. In theory, having full open windows so that one can see the dancers from the street is questionable at best. I would concur that they should do something about the window situation.
Scorpion is 10 Baht cheaper for Tiger, so they get my vote for a late night place to visit. Whether the girls are available for outside activities I have no idea, but given that most of them have tattoos, I would suspect that they are available for the right price. No doubt, the price is higher than the free lancers.
I suspect that everything will be resolved completely once Farang Alley is torn down. Without Falang Alley, there will be little support for Tongs and Scorpion, especially if the new location for Falang Alley is offering much of the same stuff at cheaper prices.
Only time will tell. Udon is changing - and there are those in the local government that would like to see changes to avoid Udon becoming another Pattaya or similar places. For that I applaud their efforts and will basically support them completely. I am of course against too many restrictions - but hen again, we do need some restrictions.
