Well. I once had a producer invite me to lunch at a very exclusive and expensive restaurant whereat he sat eating lunch while I sat and watched him. When he was done stuffing his face, he gave me a load of bullshit over our bill for services rendered on his crappy film. I was very happy when the executive producer fired him. What a douche.
Mostly it's mystery meat in a sack. Ahh, the glamour of Hollywood.
