Yeah, maybe Jspy86 exaggerated slightly. She seems very nice and classy to me. Especially if you have a Playbill with you I don't see why she'd "quiz" you about the show. Maybe she was just asking if they liked a certain part of the show, and the poster mistook the information. Just want to get one thing straight though, she doesn't take individual pictures with people, correct?"
Right, no 'selfies'. She doesn't pose with people, but you can take pictures of her while she's out and signing.
To answer the other questions: I believe she exits out the door next to the designated stage door, but security typically has the barricades up before the show lets out, so that gives you an indication of where she will exit. And, as far as stage doors go, this is NOT very crowded. if you don't manage to get up front, you can ask people to send your playbill forward, or you can send her a playbill through the mail and she will sign it. Not only will you get her 'best quality' signature, but she will inscribe it if you ask. She's very quick when it comes to answering fan mail. It took only a week and a half and she signed and inscribed both things that I sent to her. Here are some 'crappy' pictures from my first stage door at The Audience. I was shaking because I was excited to see her so the photos didn't come out well:




"Mostly, I loved the size of these people's emotions. Nobody has emotions this size anymore. Outsized emotions. Operatic emotions. Kushemski and Vanda are like Tristan and Isolde, they're Paolo and Francesca. Nobody's in total thrall like this anymore. Nobody's overcome by passion like this, or goes through this kind of rage."
