The Nurses and receptionist that are in the Emergency room do understand that most are their for a real emergency but honestly some peoples so called emergencies are just that.
Some people come to the emergency room when they really don't need too.
The emergency room staff have to make sure that you're having a real emergency and treat the ones with the real emergencies first.
Such as someone who was seriously injured in a car accident would get treatment first over someone with a broken Arm. Which is the way it should be.
There's not enough surgeons or nurses for every person who shows up in the emergency room.
