Word. If you're gonna bother to come out, you can pay a little attention to the people who are waiting there to greet you. I'm not talkin excessive, don't expect to have conversations with them, but signing playbills and acknowledging compliments seems appropriate. "
Okay, man, this post was so good that I had to respond.
Anyway, actors do not owe you anything. They already entertained you, which is what you went there for. I doubt that people pay $60 or something just to get an autograph (At least I hope that isn't common!

). They get entertained by these actors who have to work up there.
These actors can be dead tired after the show- who SAYS that they have to come out, paste on a smile, and sign your playbill? If they want to go home, or NEED to get home, why should they be forced to stay, sign, and talk?
I'd rather have an actor that comes out when they have time to face the fans, and can be gracious out there, than one that needs to get home, but feels forced to stay behind and then isn't that kind at all.
And the die hard fans at the stage door are not usually the ones that cast these actors. And it's their decision whether they feel that the way the act towards fans affects their career. If it makes them seem unfriendly and ruins their career? Their problem, not ours.
