My girlfriend, who estimates insurance claims for homes and then is the project manager when she subs all the work out, has asked me to be her painter because she knows I do excellent work. So, I just finished painting two different jobs for her that required a lot more time and effort than she originally said it was going to be, plus she snuck in a couple of extras that we did not originally talk about either. I know I should have told her that I wanted to see the jobs myself first, but I figured she knew what she was talking about since she's been doing this for so long. Well, now the work is done and I feel I got taken advantage of. How do you quote a job that's fair to the both of us? Also, how can I tell her that I think she took advantage of me without hurting our friendship? Someone please help.
