I met the Bangkok twin first. He had a well-run upstairs bar in Patpong (probably the best one of that type). It was called The Fire--- (-house, -place, -side; can't remember now, this was the seventies) and I think his name may have been Vinai. Never heard anything about him being a policeman although he was obviously well connected. I went to John's Place in the early 90s and mistakenly thought it was the guy from Bangkok. We had a mutually confusing conversation until we figured out what had happened.
