What do you think of me refusing to examine my best friend's private area and then cutting contact after he posted a bad review of my practice on google?
Why would you do something like that?
I can't risk losing my reputation for this.
You should find a way to work this out without cutting off contact. It's not a good way to keep those important to you in your life.
What if they take my reputation and still left a bad review.
His bad review has nothing to do with his friendship with you and they should be completely separate. Instead, you should just refer him to another doctor since he thinks so poorly of your work and then remain friends with him.
