eye dr. appointment for sj...are they testing his patience or his eyes?

SJ had his annual eye doctor appointment this morning.  We arrived at 10:05 am for a 10:15 appointment.  We didn't get called back (into the smaller waiting room) until 10:45.  The boys were moderately well behaved in the big waiting room.  Bob was on his DS and SJ was playing at the activity table.  When we were first called back, SJ was getting in and out of the exam chair.  He was fussing with the plastic rug (for chairs with wheels).  He was standing in front of the reflected alphabet eye chart.  I repeatedly reminded him not to touch the doctor's instruments, but he is a child with a very short attention span.  A few minutes after we were in the small room, the nurse came in to do the preliminary eye exam on SJ.  He did as well as can be expected with the nurse.  His eyes haven't changed, so there is no immediate need for new glasses.  The nurse left and said the doctor would be right in.  This is when the behavior started to get hairy.  SJ was acting very hyper and wouldn't leave Bob alone.  Bob was getting frustrated with SJ, so he wouldn't even let him watch him play his DS.  I threatened with the "no electronics", but in their defense we were waiting over an hour.  Finally at 11:10, the doctor came into the room.  He spent about 3 minutes with SJ.  He did the more thorough exam and said he would see us in a year.  It just boggles my mind that doctors make any child wait so long.  For a child like SJ, it is inexcusable.  As we were driving away, I wondered if doctors ever get frustrated when they wait for an appointment.  I am sure if they had a child on the spectrum they would think twice before testing any child's patience.
