I have been taking care of this crazy client who is rude and verbally abusive. When she doesn’t get her own way, she shouts and screams until things are changed. I can’t do anything but continue to serve her, as our company can’t afford to lose this multi-million-dollar account. I have spoken to management to try and switch, but all the other accounts are taken.  I don’t think I can take it anymore. Any tips on dealing with such an unreasonable person or should I just look elsewhere?
