You should try walking in with a fractured maxilla (upper jaw) and teeth still in their sockets but knocked back into the middle of your mouth. I was sat around for hours and even when I was seen and sent for x-rays, I had to wait hours more for them to call in an emergency dental/maxiofacial guy who promptly grabbed the teeth and pulled them back to where they should be without any aesthetic - at which point, I (much to his alarm) pulled both arms off the chair I was sat on.
Oh, and I was stone cold sober at the time....
Last time I had an emergency, I took myself to the eye hospital and yes, there were plenty of folks sat around with obviously very minor problems. Fortunately, they had triage in place and I was seen almost immediately, diagnosed and although they couldn't treat me right away due to an emergency, I was scheduled for urgent surgery latter that night.
