A few years ago I spent a week in Berlin, intending to party after having heard its reputation. The clubs were a parade of "oh, you don't know who's DJing? Can't come in" and "you're wearing a scarf, can't come in" (it was December, so cold and presumably not peak partying season). At Berghain it was something like "sorry, private event." Fuck Berlin clubs, if they want to turn down customers trying to give them money, let them succeed at their attempted suicide.

(Having said that, while having what was supposed to be my last drink of the entire trip on my last night, I met an Austrian guy who told me about some club in walking distance he swore was good, so we went and it in fact was so good I missed my flight the next day, so it's not all clubs that are raging dickbags to would-be customers at the door, the exceptions are just hard to find.)
