It may come down to your word against his when explaining to the police, unless there are witnesses willing to go out of their way to help. In such a place as Macro, security cameras may not have quality enough to see the spit, but they will certainly see you retaliating by throwing the first punch. Either way, if the mood strikes immigration, they just might say two farangs are fighting...send them both packing. Problem solved.
I enjoy my life here. I'm not willing to risk being deported because someone spit on me.
