me too... but if it did happen, i'd probably barf on them. oddly enough spit is the one human body fluid i can't handle. i'm gagging just thinking about it..
Break their nose or end them. If it's a woman I'd probably spit back and call her fat. I'm a gentleman.
Act like some of it got on there face, you go to point where it is only to punch them in the throat. Doesn't matter how tough a person, getting hit in the throat will stop anyone.
