This is less about being a c00n, and more about how you treat people...
People can deal with "diva" attitudes and whatnot, Whitney and Mariah have many people come out and say they were tough to deal with, but in the end, bringing them on brought more people (money) out and it's cool. Can't be a dikk to everybody then expect them to want you back, especially when you're replaceable.
I understand the money thing, and wanting to be paid, but to ask for bread or require it for EVERY. THING. YOU. DO is a bit much. These white execs will just tell themselves they can find another you. In every aspect doesn't matter how rich you are or poor, life is about bartering. Using what somebody else has to get what you need. Working together. Can't NOT promote a movie cuz you need payment everytime you leave the house then expect to get MORE roles. Yeah, I don't support c00ning, but I do say if you're LOOKING for approval or awards, then you have to do what THEY require you to do or you not gonna see a dime/thing...scratch my back and I'll scratch yours...
