Phew!
Havent done doors in years...but I did do the course.
The course is easy, since the people doing it will have the intelegence of a dim witted gorilla, and their companies want them to get through. If its anything like what I did, you will be given the answers first, -just write them down.
As for doors, just beware of drunk women...and conversley, work with a lady yourself, as the presence of a female often defuses situations (unless its the aforementioned drunk women...)
Cant recall much else.
Here is a friend of mine ex nightclub bouncer when Cov was a very mean place the door was a scary place I worked the door of the climax and a few others for extra cash I was also a member of mensa, set up specialised Demetia unit which gained a centre of excellence and this is what Geoff achieved not bad for dim witted gorillas. https://en.wikipedia.org/wiki/Geoff_Thompson_(writer)
I'm a big fan of Geoff, his books gave me the confidence to start my journey in martial arts 20 years ago, one of my sons now trains at the gym I got my black belt. His honesty and openness on both the physical and philosophical aspects of life that he struggled with helped give my life a nudge in the right direction at a critical time and I'm very grateful to him. If you still see him please pass that on.
When he used to run the animal days it was what it looked like brutal but it was to pressure test your skills as a martial artist or indeed a street fighter no one asked your discipline your performance on the mat spoke volumes about the man/woman, I first trained with him at a school in Wyken, years later we are both different people to who we once were, I do email him when I have something I would like to share such as creating your own reality which he incorporates into his talks at Coombe Abbey, he is now a very humble man who has never forgot or hides his background, When I speak to him again I will pass on your gratitude
