tshadowchaser's last comment is one that should stick with you above all others......leave no room in their mind that you will do your job.
i was the head doorman at a relatively small club that held about 500 patrons, and it was known as a rough fighting type of bar (not a totally great place to get my first exposure in security) and there were only 2 other doorman besides me. my first order of business when i started working there was finding out MY rights as a doorman, and the PATRONS rights. this was so that there would be no error in my mind when it came time to do my job what type of force i was allowed to use, if it came to that. after i worked there for awhile and became aware of the law, i managed to get them to hire more doorman to become compliant. i didnt get the head doorman job right away, that was my teachers job.....he was an experienced bouncer and taught me alot about learning the the crowd....after he left, thats when i was promoted and my real education about fighting took place.
rule #1. never turn your back on anyone.....be nice to the patrons, but remember, you're not there to be their friend and lots of guys that have had bottles and ashtrays smashed over their heads will attest to this.
rule #2. idiots travel in packs, and bouncers move in pairs. always have a right hand man, or be someones right hand man to learn the ropes....back this person up no matter what, he could save your life, or you his. i know this sounds serious, but being a bouncer is not a laughing matter.
rule #3. learn how to make a wall your friend. lots of times i have seen guys backed up against a wall getting the $h*t beat out of them by one or several others. this should never happen(see rule #2). but if it does and you dont know how to defend yourself in this position......look out.
rule #4. NEVER i repeat NEVER let a fight go to the ground.........this is not brazilian jiu-jitsu, this is bouncing.....you fall down and you will have loads of opportunists that dont like you jump on you and try to get their licks in(think im kidding?) all fighting does not go to the ground, no matter what the gracie's say.
rule #5. never let a patron put their hands on you......they will do this under the guise that they're being buddy buddy with you (and maybe some guy is) and then next thing you know some amateur judo or shootfighting wanna-be has you in a compromising position.
