It would seem the American tourist was complicit in the violence which resulted in his broken nose. Seems he has a weak standing, if any, to lodge a complaint. Normally I would be critical of the minimal 1,000 baht fine to the security guard. In this case, its a token, but at 4 AM after a customer, no doubt drunk and belligerent, engages in an altercation with a DJ requiring the intervention of 3 security guards, its difficult to have even a shred of compassion. He got off light with a broken nose and a hangover. He tarnishes the reputation, be it as it is, of foreign tourists to the kingdom.
