I've just lost two stone. I'm only 20 stone now!!
I worked on the doors for 3 or 4 years and have seen some big fights and seen bigger people knocked to the ground by much smaller men.
I have far too much respect for peoples stupidity to think that they give a toss how big someone is. You will never beat a piece of wood round the back of your head, a knife in the stomach or a gun.
If people are prepared to kill someone for looking the wrong way then the wrong person protecting their 'patch' may just be your worst nightmare.
