It really depend of what nightclub you go to, i did once and it was for work, but i realized that there is two type of nightclub, the one everyone go to, open to most of people, and THE nightclub, the one where women are really acting like whore without a shame, even if you point a camera in front of them, it's selective nightclub where woman are selected because they are hot and act like whores, the more they look like a whore the more they let hem in.
Also there is the lgbt nightclub where it's expected from clients to act like sexual animals, they even aks you to come in the most depravated cloth you can find, fun fact many heterosexual woman go in to dance like whore without having to talk to sub5 who think they have a chance with them.
