"Sat in the orthopaedic clinic"

Would like to know why when there is three doctors on a clinic why my appointment was when the clinic started. Yet three quarters of an hour later no one has been called in. Can three doctors really be delayed? If they have been why have the nurses (who are just stood around chatting) not actually told people this. Why have they not even bothered to update the board which just has the name of the doctors on. Why do the people running his clinic think their time is more precious then mine.
