Alicia Keys dissapointment

First saw Alicia Keys (http://www.aliciakeys.com/) at the Tower Theater in Philly on her 21st birthday. My wife enjoyed her music and I was a fan simply due to her covering a Prince song. Then we went to Atlantic City for a charity meet and greet with sound check included. Well the sound check was great but she wasn't there. Then after the show those of us with the meet and greet were herded into the depths of the Casino basement. After what seemed to be a 20 min walk to her "dressing room", we got to meet her. She stood in between two curtains, and graciously shook our hands while signing a black and white photo with a black sharpie on a dark part of the photo. When I asked her to sign something I had brought, she replied, "I don't think I can sign that", to which her security muttered the same thing and asked me to move on. I was instantly turned off by her lack of concern for the amount of money that was spent on the chance to meet her and then brushed off like an irritating insect. On the good side, my wife still likes her and her music.
