I agree on why they have their fights ..... most of these guys are drug users, heavy gamblers in debt, heavy drinkers, crims who have police files against them, guys who can't get a regular job at a factory or workshop because of their past history. Having said that, there are one or two who are clean and do it to earn extra cash. I try to give them all a wide birth but unfortunately one has to use them occasionally. I wouldn't trust them as I don't any thai.
