I've been close to getting into a fight but nothing ever happened. Gotten to the point where adrenaline starts pumping but nobody ever has thrown the first punch just pushing.
From doing martial arts I've been in a lot of matches including with my fists in MMA and boxing but I haven't been in what I would consider an actual fight since I was in middle school. I agree with the other posters that if at all possible a street / Bar fight should be avoided. As I tell my students you can be the biggest bad ass in the Dojo but a street and/or bar isn't a dojo.
LOL by the way, this thread prompted me to do a search for "Harry Palmer" on the RealGM forum (Macbeth's user name there). NOT pretty. I would post some of the gems I found but that would only allow Bat****crazy Jones to accuse me of stalking again . But if someone says they are curious...happy to share. Let's just say he seems to have the same issues there he had here. Strangely, there was also a thread with a user impersonating Clutch and saying all sorts of weird things about MacBeth/Harry Palmer that were over the top.
