"Wild Goose Chase?"

I came early, by patient transport, for a 2.15 appointment, but was not called until way after that time. I was then sent for an X-ray (unnecessary, because I had one at the time & place of the accident) & told to wait for news of an outpatient MRI appointment. So: Was my visit here, today, really necessary? It is now getting on for 6pm as I wait for further (superfluous?) patient transport.
