First off, I can see why people think it is slow, but they also have a sign up saying you will be seen in order of priority. Therefore, if you are not gushing blood you can wait awhile.
My girl broke her wrist so we spend few hours here maybe two, but the nurses were nice to her and even offered to fill out all her paperwork for her since her wrist was broken.
So I have to say that's good customer service. ;)
