Idina's job ends when she steps off the stage. She is criticized a lot for being quite/bitchy/cold/blahblahblah at the stage-door, but the thing is that most of the time she DOES go beyond the "call of duty" as you call it. Obviously in this case she didn't, but usually she signs for a lot of people after the show. She may not do it the way people want her to, but she does none the less.
/Warning Stage-Door Story/
I took my niece (who is eight) to see Wicked, and Idina was very sweet to her. She is very friendly and tends to think that everyone wants to be hugged(my niece- not Idina) so when it came time for Idina to sign her program she wrapped her arms around her and said "Your better then the real Wicked Witch."
For a moment I was thinking "Oh, ****," because I had heard so much about Idina being un-friendly, but she hugged her right back and said "Thank-you so much sweetie!"

"A wonky eye, you've got my friend."
