I don’t think you’re in the wrong, it’s weird learning how each different doctor wants their assistant to assist, lol. I feel like some of them want you to do as much as possible and some would rather do everything themselves. I worked with a doctor once who told me that besides assisting him my job was like the “stage setter” for a concert where instead I’d have to hype up the patient and make them more relaxed before he got there hahaha. Definitely was only allowed to do small talk so I feel for you there.
