I'm most interested in the context of this scene, is the waitress part of a staff that serves refreshments in the buff, I love the fuzz-less vagina.
They're at some high end fancy party that's hired nude waitresses. I don't believe it's supposed to be taking place at some sort of nude restaurant or anything like that, but that she was just hired for that one specific event.
People on other forums have been trying to identify this girl as well, like here (click "enter adult dvd talk" to see the discussion). http://forum.adultdvdtalk.com/id-the-nude-waitress
but I didn't think anyone has had any luck. It might be her only acting role ever, but if so she had the most memorable and spectacular 3 second acting career ever!
