here in italy pubs and other businesses and companies regularly organize big parties guys have to pay in order to attend but girls (for obvious reasons) don't. so some American girls asked me about an "event" given by a disco and they couldn't believe they could get in for free because just they were girls. isn't it this way in the us?
I'm pretty old but when i did actually go to clubs... sometimes women were free, sometimes both had to pay, in theory, but there was a lot of discretion at the door at busy clubs, in terms of who they let jump the line etc. Clubs aim to have around 60% women if they can - interestingly both men AND women seem to prefer it.
Unless they're the guys standing outside not getting in.
sometimes they have that, some do it on like Tuesdays or whatever, some give discounts, some let girls cut, some only let dudes in if they have girls or more girls than guys, some clubs have bouncers that make bank by having guys wait out unless they give them some Jacksons on the low low. It depends where and what kinda club. You see that shit more in cities. Kinda suck, but hey, it works.
