the dress code thing works for real.
i have legit seen men and women when i was early 20s refuse to go to clubs because they couldn't wear jeans or sneakers. not saying they were violent type but they were most def on the ratchet side of the track
oh, another thing that works is high covers for men, like $20. people don't actually want to act a fool if they payed $20 to get in, and the male to female ratio has to be on point because men start acting an ass when they are hating on dudes getting women and they are standing around looking.
