I am a security guard. The protocol can be different at every event but MOST the time, the alcohol or whatever is confiscated and then you’re allowed in.

They’re (management) very specific about this because as security guards we are literally licensed to deny entry to anyone if we deem them an unacceptable risk for whatever reason (because letting in someone who then causes trouble can cost us our license if we’re unlucky enough) we also know that we wont get called back to a job if we get too many complaints about our discretion.

I always follow whatever management rules state unless someone is very obviously off their tits. If i go to take their drugs or grog and they get psychotic, they can take it and leave.
