I'm right there with you... It is SO annoying..
With the OB/GYN that I am seeing right now I have NEVER waited for less an hour past my appt time. Unfortunately he is the best surgeon in the area so I'm probably going to stick with him anyway since I'm probably having another c-section
I agree with buckner, if this doc is the best stick with her but if she isn't something special I'd say ditch her.
