Eye Doctor Appointments

Why do eye doctors schedule several people for the same day and time, and why do we put up with it?

I once had an eye exam appointment scheduled for 1:00 P.M. and even though I got there 10 minutes early, I was 9th in line. After a 90 minute wait, I finally met with an assistant who dilated my eyes. About 15 minutes later, I heard someone say that the doctor was on his way to the clinic. With all of these people still ahead of me, I got up and walked home. What arrogance these people have! They think they are the only ones whose time is valuable.

You don't see that happening (pun intended) with any other medical specialty.
