My experience with ER is fairly good. I had to get there a couple of times.
One was a severed tendon on the pinky, the other was a 3 inch cut in the palm that happened to sever a nerve.
In both cases I had a surgeon who started his shift less than two hours before I came in. Both admired how sharp the blade must have been for such a clean cut. They also did a very fine job. I regained full mobility with the severed tendon. Most of the function of the severed nerve is back too.
I also managed to get a scratch from a broken glass pane. It merely damaged skin and required only 6 stiches.
In all cases I had to wait less than an hour to see the doctor.
The nurses were reasonably pretty and had a good sense of black humor.
