There are different classes of bouncers weither you call them security, crowd control, person redirectors, privite event staff or just plan Bubba. Just plan Bubba will work the beer bars (live band on the weekends joints) like around PB and other parts of San Diego beaches that I'm familar with. Bubba will be very large but slow in wit and thinking ability. He will be strong as an ox and may use blunt force. Bubba may be black, white, Samoan or mexican. He will grab, grapple bum rush out the door any one he gets the OK from. Usually the bar manager. If Bubba needs a background check it will be forgotten or just made up for the ABC records. Bubba will make beer money and not much more. May even get to nail a few of the older women drunks at the end of the night.
The upper class bouncer (remember they are still bouncers for want of a better name or duty's) will usually be a former Israeli special forces agent (they call them agents) along with former British troopers with experience in Northern Ireland and portions of Africa. These guy's speak more than one language which can be very helpful. Retired U.S. navy seals and special forces are also recuited. Intell now-a-days is more important that just physically removing a potentional trouble maker in a crowd/event. Upper class bounchers work mainly high cash flow event, auctions, ceo gatherings, etc. A steady worker can earn in the six figure yearly income. Highly bonded & insured. Higher class women (and some prime hookers) are usually attracted to these guy's. And one that I had know before married a very wealthy lady. Lives in Brentwood last I heard.
Then there are the mid-level bouncer who works at clubs, sporting events,concerts, new movie openings, etc. Club gigs are the most dangerous jobs. The bouncer may or may not get a voucher for emergency treatment in case of being cut, shot or hit with an object. These bouncers are hired for size, height and having a bad to the bone look/attitued. Will usually hold a background in boxing, fighting, etc. Most often ex jocks. A few have done joint time in front of or behind prison bars. Seems more brothers are being hired than ever before lately. A few Mexican & south sea islander's are being employed more also. But a lot of white boys are still in the mix. They tend to be floor/pit boss. The most dangerious time for any of these bouncers is after 2 am sunday morning in any bar parking lot. You must leave after hours in pairs and have come in the same vechile for safty sake. Of course if any one hooks up with a hottie than their on their own. They will usually be require to be bonded which in most cases doesn't mean too much but looks good on a legal contract.
BB'er make poor bouncers for the simple reason that they do not have the experience of handling a out of control drunk or some other hot head. You have to have the knowledge of handling two or more sometimes and try to talk them down at first. BB'ers for the most part do not have the holding or redirection skills of showing a trouble maker out the door. Bouncing is a lot like having football, wrestling or martial arts (not karate which has way to many flaws for it to be effect in a tight crowd) skill's of using leverage and weight/pressure against an unwilling person(s) who does not want to go in the direction you want him to. A bouncer does not want to throw a punch ever. Those 21" guns may look great in a mirror but actually using them in a possible real life fight is a far different thing.
A good bouncer is above all a thinking person who will prefer brain power over brawn but will still reley on his size, strength and look to establish his rule over any unexpected troublemaker. He will also workout heavy on a regular bases to still get stronger. I've worked out with quite a few of them.
