I am a nurse or was a nurse up north. My doctor was always late. He never rested or loaf.
The reason he was late is that he cared for his patients. I don't know how many times he would be done with an exam only to have a patient start in on many many issues. This of course would make him late for the next patient. It would be one thing if he was in and out of the room but all too often he would find or discover a problem that would need more time and follow up or the patient would be scheduled for a yearly and then start asking him to remove moles etc etc and all of that took extra time.

The patient that was waiting would get his full attention when he was in the room with them.
BTW I tried to always let my patients know what was going on and bring them magazines to read.
I am not saying this is the case down here but it is my experience.
Also if the doctor is not in the office yet....he may be at the hospital taking care of someone.
