My only complaint is having to be there 15 min before the appointment!  If I precheck in then what is the point of sitting in that waiting room for 15 MINUTES!? That is an extra 1/2 hour of time out of work because I have to leave even earlier and the sit and wait!  If I am not there for the appointment it is because something happened to me, and you can just go to the next patient.  So why is it such a big deal for a person to be there early?
