I'm not sure I would mark this as fake. I've been there twice in the past 30-days or so (yeah I know... I have a problem).
And both times went per the usual there. Granted, they know my fake number when I call, so I am already on their good side before I get there.
I can't speak regarding Mimi, because I've never been with her. However, I've had great sessions with Amanda, Lucy, and Sue.
That being said, you should always be hyper aware of the situation you're walking into. And keep in mind, if the girls playing it legit, maybe they know something you don't about who is watching.
