strip clubs are not an easy start option mate trust me
rather than worrying about the door you should be concerned with the reputation of the firm you are approaching to work for- are they professional, do they have good lads working for them, will they back you up if things go wrong? that type of thing
then you just phone the firm, tell them you have a badge and take it from there- you are going to be clueless when you start, so be polite, listen to what the more experienced lads tell you to do and try and behave in a professional manner at all times
this isnt really a doorwok forum and most advice on this subject given is pure bollocks so I dont really want this thread dragging on
phone a firm, get to work, let us know how you get on after a few nights
all the best mate
