I've been in the ER with my son for almost 6 hours. It isn't even crowded. We were finished hours ago and they won't discharge us. There is a patient in each room requesting discharge papers. I overheard the nurse politely ask the doctor for a timeframe and he told her when he was done.
I drove several hours to bring my son here because he attends school at OU and was sick. It is the middle of the night now. Maybe I'm spoiled, but where I am from, doctors don't treat people like this. It's rude and inefficient. I have spent less time in the hospital for a surgery. I don't know how this place stays open.
