No but I had one bizarre experience back in about 2005. On a road trip with my family, just starting out from Chiang Mai, we stopped for fuel on the superhighway heading out of town. I went to relieve myself at the urinal around back, as one does, and there were a couple of guys doing the same. While we were there, another Thai guy came in, saw me there, and started talking sh*t out loud, to the effect of, "Look at this white guy in here, I guess he's not afraid of getting his a$s kicked. We could take him down." (in thai it was something like, oho, mee kon kaow duay, mun my gluwa don dtet rue? ow mai la?") I took a quick read of the other guys, who seemed uninterested, so I zipped up, turned around, and gave my best expressionless, cold-eyed stare at the talker to let him know I understood what he said. He shuffled off. If those guys had been game, I would have been totally f*cked. Again, it was one event in like 30 years, but still a reminder that there are some psychos out there looking for trouble.
