I got scam the same way over ten years ago at Patpong, I was threaten in the bar.....
Patpong scams can be reported to the Tourist police. I heard that they have an office somewhere in Patpong. They're suppose to be able to speak english. I'm surprised that those scams are still going on after all these years
You never know about these places, such misunerstandings can lead to somewhere most would like to avoid. I read about a Sporean who struggled with someone & got shot dead. Turns out the man he struggled with was a policeman
With the notorious reputation of patpong it's easier to avoid that place & just go to Nanna Plaza, Soi Cowboy, Ratchada,...
