'Don't mention the NVQ'
Why the devil not?
Whilst not being a particularly large chap myself, I'm currently doing the course (which is now required to work as a doorman). Door work is surprisingly well paid and whilst the course itself is not particularly difficult, aspects of the job require pretty good people skills and the ability to keep a cool head under pressure whilst dealing with difficult situations/people.
The fact that you work as a doorman is not something that I would try to hide, though it's also not something I would brag about
