It sounded like they went out of their way to make it an adult activity, which is bad for the cause of nudism. They have, excuse me for putting it this way, perverted nudism. I think sophomoric is a better word to describe it. Drinks afterwards, with topless waitresses?
In our contemporary American society, anything having to do with nudity, at least mixed nudity, is nearly always treated as an adult activity with a heavy dose of ribald humor, which apparently goes over well in most places. So-called "gentlemen's clubs" seem to do well in places with a lot of churches. Alternatively, it is seen as something exceptionally immoral and threatening to the very fabric of society, especially in places with a lot of small minds. But there are exceptions.
