There is a lot of good tidbits here,
I worked as a bouncer for year to earn extra cash and getting to see some good bands for free didn't hurt. When confronting people who where acting inappropriately I was very nice to them. They would try to intimidate, puff out their chest, swear, yell and all that, but in the end, treating them nicely brought them back down and they would leave on their own two feet. I even had a few people come back the next day and thank me for being nice. I'd say this worked on about 99% of them.
A good choke hold worked on the other 1%.
