The whole 'flake' thing and listing girls, agents, producers is dangerous and does nobody any good.
I've had some of my super talent, always show up early, etc, flake on another producer because they got bad vibes from them.
I've had another producers, 'best talent ever' flake on me once or twice, then worked like troopers for tons of scenes.
Everyone has a bad day, off day, even me...rarely though
If you're going to make a list, make an 'at-a-girl' list, with positive responses about talent that:
-show up on time
-show up ready to go with a sweet attitude
-know how to perform like they like it
-can scream, talk dirty and fuck the guy silly
That's a list that seems more productive to me. All the negative bullshit doesn't do anyone any good.
