I don't know who that guy is FM but doubt I would be in that class. I did work as a bouncer in an on premises swingers club for a few months in Miami which I thought was fun. It is now gone so I can tell you the name, Playhouse South. It was owned by some old friends of mine from the CIA if you must know since both are now dead.
Body guard work was mostly boring in that you travel with some guy/girl that is scared of their own shadow and no one really knows who they are much less cares. Courier work was kind of fun but not really dangerous in that I would fly with something, usually first class, then be picked up at the airport by embassy staff and taken to an embassy. Once done back to the airport and on to the next job.
I guess the best job I had was for two years in a row I went to Costa Rico with a rather famous drug lord's father who had alzheimer's to a whore house. This was his son's birthday present to his father. Well the first time the old man (86 yr. old) picked out 4 women and spent a week in a room with them. The second time was pretty much like the first except he fell coming down a fight of stairs leaving the room, breaking his hip in the process. He died before the next year so that contract ended.
Another good time was going to Montana Deer hunting with an Arab Sheik and once getting there they found out deer's have a split hoves hence against their religious beliefs to eat. Me and the other two body guards left them (15 people) in their cabin while we went deer hunting and got a good one too.
Now I also did some serious security work from time to time with the down sides of that being many. It is also the reason I finally quit doing it. Those down sides would be a bullet wound through the left fore arm, 24 clamps close my stomach which was cut open by a machete in a jungle in Nicaragua while traveling with 20 mercenaries, a month in a Columbian prison and being a passenger on a helicopter that fell out of the sky when hit by ground fire. Hence I'm happy I'm still alive and those I told are only because those involved are dead.
