It would drive me nuts. My T has a nice set up with 2 comfy armchairs facing her chair. My pdoc's office isn't really set up for therapy -she's mainly a hospital pyschiatrist and sees only a few private patients. So we usually sit across from each other at the table in her office. It always makes me feel like I'm at a work conference , but she's a great pdoc and I love her. My addiction's Dr. likes her barriers - she keeps a couple of low tables between her and her clients and the chairs are really far appart. It feels very formal to me.
Worst set up was when I was seeing a replacement pdoc, because my pdoc was on medical leave. He had a tiny office with only one chair beside his desk. So he was at his desk and I was beside him, I felt like I was just another patient to be processed as quickly as possible.
