"Delay in being seen by consultant"

I was given a 9.20am appointment with the consultant at Fairfield Orthopaedic Unit and arrived at 9.05am in the waiting room after registering at the reception. I then had to wait until 10am before being moved from one waiting room to another outside their room. The consultant then left the room and I and to wait until 10.30am before finally being seen by them. The nurse was less than helpful and we got no apology for the length of time we had to wait. A young gentleman sat opposite us had been waiting longer than us and another couple whose appointment was five minutes after ours were thinking of leaving due to a train their daughter had to catch. There appeared to be patients arriving after our appointment time, being seen before us. This is extremely annoying and after seeing the consultant, I was asked if I could have an x-ray. I explained that I had a dental appointment at 11.20am so had to leave. Considering most appointments only last five minutes, why do you have to wait so long without an apology.
