The doctor sat VERY close to me and in a way that blocked me from the door and made me feel uncomfortable. I don't think that was his intention, but I'd encourage him to be mindful of his proximity to patients and making sure they don't feel trapped. He sat in such a way that he was reclined from the wall to the patient table so it was blocking me in as I sat in the chair.
