Mainly because of lack of room, and safety. They don't need 10 people in a small treatment room when they are trying to help a loved one. And before you say anything, I have seen it, and people don't have respect for the patients next to them. I'm not trying to be negative towards you, but do you want a bunch of people in the room next to you being loud and disreputable if you were sick enough to be in the hospital.
I think that it means I'm the back we're they are treating all the patient there's not much room the ER stays full
