Any time I had a question/concern, he didn't seem interested. Any time I made a comment that might engage him (I mean, relevant), he kept coasting through his routine. At first I thought it was odd but since it became a pattern, I realized I'd prefer a doctor who was more interested in me. I don't mean to sound self-centered but that's what I came for, right?
