Who’s allowed in your physician’s lounge?

So curious to me how much it varies hospital to hospital. I’ve been places where residents and mid levels were turned away. This new place I’m at is literally 50% admin folks. Tbh sorta feels uncomfortable. There’s also a lot of people in here I never realized existed like anesthesia assistants, perfusionist, other various titles with letters I don’t fully understand. Follow up question, who is allowed in your doctor’s parking area?
