I was there for a radiology appointment. I waited for an hour or more (I stopped counting the minutes) and watched people who checked in after me check in, be served, and leave. I was absolutely livid as I came in for an urgent scan, and the excuse I received was that there were a lot of patients. While I understand this, I am still angry that I was there for over an hour waiting to be served after I watched people who had arrived AFTER me be served BEFORE me.
