What's the point of making a doctor's appointment if they never see you at that specific time?

Asked by tinyfaery (44107) September 23rd, 2009 from iPhone

I made a doctor’s appt. for 8:15am because that’s the first appt. of the day, yet it’s 8:36am and I have yet to see the doctor.

I don’t get it. I don’t think I have ever seen a doctor at my appointment time. Is there some sort of conspiracy going on?
