All I can add is that if I walked away from difficult projects (or in effect did so by doubling my price) I would have very little of worth on my resume.

Physical threats I wont tolerate, but I've had someone threaten to throw my drums out of the window (several stories up) if I didn't play the way they wanted me too.
That album is still loved by many and I often receive compliments on my performance.
