Nothing ever good happens at 4:00 am. I'm sure the Brit was pissed and then got into it with a local or two. One thing I learned long before my wife taught me is that when you fight a Thai you are fighting 9 not just one. Keep your head down, ignore the comments and keep moving. I can swear rightly in Thai but, my wife has always told never to do so and I respect her advice (aside from the fact I'm getting to old to scrap with people a third of my age although I could probably take them but with knives and guns and what not, just stay quiet, plus we're pretty much done with the past 12:00 am bar scene, nothing but trouble- mostly for me!)
