Red, I think she deserved more money than what she got, because of the abuse. That kind of behavior is uncalled for! Your cousin was trying to solve the problem, and he should have been more patient to keep working with her, because she was determined to do what was right by him, and that was not very nice of the guy!
They say where there is a will, there is a way, and I have made things fit before that were not supposed to fit, so I'm not so sure that the guy couldn't have made it work, anyway, he would have been more kind with your cousin!
