im guessing they are more than welcome to give you a patdown of somewhat... this would be checking for weapons and objects that could inflict pain. But when it comes to a having ur wallet searched and everything else, i think that is a different story.
Depending on the venue, bouncers are usually half decent, they are very egotistical, because they have the power they use it, and because 9/10 of them are wired, it is easy for them to kick the fuck out of a punter or 2 in a few seconds, im sure, if u were in a group of about 20, lets say for a bucks night, and the place u were at only have 5 secca's i bet they wouldnt try to start anything with u...
i work in a shitty pub, but out security are have full security licenses and all that shit. I asked them about our rights and what they can and cant do...
They are allowed to ask us to EMPTY our pockets, while they do a beeper test on us, but they are not allowed to actually PHYISCALLY lay a hand of us, that includes pat downs and so on. When it come to checking your wallet, that is invasion of privacy, they have no right at all to check your wallet, so if they ask to see into your wallet, you so NO, its against ur rights, FUCK OFF, of course in a gentle way, maybe just ask why. if he says anything like, Coz i wanna see how much drugs you have, you say no, ur not allowed, he will then probably kick you out of the line, but i have been told if this ever happens, just to take down his number, and report to the pub/club/venue manager immideitaly.
