A new ENT clinic opened in my neighborhood, and the doctor is a type I've never seen before

Even though I only went in for rhinitis, while examining me,
he showed me photos from medical textbooks and research papers, explaining everything one by one—why I'm in this condition now, what needs to be done to fix it, and what the outcome will be once it's resolved lol.
I'm personally very interested in this kind of thing so I like it, but since the consultation time is long, I think people might have mixed feelings about it.
