pretty common with the bouncer behaviour, id rather pay a fee and know i wont get kicked out of the venue mid set or get charged with use and have drug abuse on my record. Bouncers get paid fuck all and have to deal with every stupid fuckwit in the club, its no wonder they do stuff like this and in the end its win win, you dont get fucked over, bouncers make some extra coin if you're careless, you go back out and enjoy the night
