I am at odds whenever somone has to use the "title" bouncer.
Being a bouncer does not equate to superior fighting or defense ability
I don't think it was used to denote fighting ability more to show that he's used to taking flak off patrons and NOT responding to them with violence. Door staff get a lot of verbal abuse of people they have to eject from the premises or move on and the ability not to repsond by smacking them, of being able to smile and let it go is an important skill.
