The difference between you and some other posters is that you are not vilifying me for doing it, just because it’s not to your taste.
But you came on, identified yourself as a former worker in a highly problematic industry, and invited questions? I don't see 'vilification' , I see people pointing out that it's not a matter of different 'preferences', as if you prefer strawberry to vanilla, it's a matter of ignoring the general social effect of an industry that normalises the objectification of women and the purchase of consent. It's not alone in doing so, no, but it does normalise it -- ie the idea that going to a lapdancing club is a normal, socially-acceptable thing to do on a stag night.
To the PP who asked about the difference between the Moulin Rouge and a lapdancing club of the kind the OP describes weirdly, though I've never been to a show, I was involved in recruiting some dancers, mostly from a rival Parisian show of the same kind, some years back - for a classical stage production being directed by a friend. (Long story too outing to give more details, but the production needed classically-trained dancers who were OK with appearing topless on stage.)
The dance requirements of this MR-type club were ferocious -- as well as being over 5 foot 9 and having the right kind of physique, the women who danced there were put through a strict audition process, required to have classical dance AND modern/jazz dance training, and to be able to learn long choreographed routines quickly. In some routines they had exposed breasts, but were often wearing heavy, jewelled costumes and feathered headdresses, or can-can costumes, dancing in unison with 50 or more other dancers.
And, given how massively expensive it is for the show and dinner, the audience is essentially well-heeled overseas tourists, not men looking for sexual titillation and private dances. It seemed more like being in West End musical, but wearing unusually revealing costumes, than a strip club.
