Getting paid?

Hi everybody! First off all I would like to say that I really loved this quote on this one website that I was going thru couple of days ago. It says; ’’You don’t see people hiring a doctor and telling him exactly how he should work. You tell him your thing/problem and hope for a good fix. The same way should work for design. ... So my question/s are; 1) How do you guys manage a client that is bothering you like crazy and saying 5-6 times what should be corrected, changed and what he doesn’t like and so on? How do you deal with that & how do you charge and what are the options? Hope you guys share your experience and opinions. Regards Vik
