Perhaps I can clear some things up. He wanted his brothel to be different so he made changes to the concept. Since most brothels the women were clothed and in dark lit conditions Bern opted to have his women wear nothing totally nude with the exception of heels.
Lighting conditions were also more natural and better lit. The club started in the basement of Bern's home. With a bar, pool, sauna and a few rooms.
Other rules were also enforced such as women could not approach the men or be aggressive. The men had to make the first move. The club charges an entry fee that includes use of the club 1pm midnight Monday - Friday.
Food, drink, beer and alcohol. Women are paid 50 Euros for about 30 minutes of time. Bern's club was in essence the first "Sauna Club" but with a twist that women were available to the men. There's another side to the thinking, in Germany what takes place in a private room between a man and a woman is no one's business. Privacy laws allowed two people to pay entry to a club working women and men if they decided to go to a private room and engage in something that was up to them.
Thus the club could operate as a club not a brothel. The club was therefore collecting entry fees from the women and men. Nudity made things easier, since both the men and women would undress, shower and be ready for action.
