Avoid paying the exit fee at Dolce Vita
I found a way to bypass the exit fee when you take a girl out of Dolce Vita. (DV charges either 75 or 100 R to take a girl out of the club with you, I think it's called a "desperta" fee on your bill).
The best way to bypass the fee? Just go up to the desk by yourself when you are paying the bill, don't have the garota standing next to you at the desk. When you get your receipt, go grab your girl and walk out of the club. They are not going to stop you at the bottom and make you go back upstairs to pay the fee. I did this multiple times on my trip last month and never had an issue, in addition, I figured they owed me money from all the times they ripped me off in the past.
Good News: I think someone must have said something to the owner / manager. The blonde woman who normally works the desk wasn't there for there during my entire vacation. They have some young guy working the desk now. I still go over the bill but he hasn't tried to rip me off the way the woman constantly did.
