It should also be used for, hmmmm, I don't know, EMERGENCIES! If you are not in danger, bleeding, in serious agony or dying, you can likly wait to seen you general practioner.
*example, not main point!* If you have a pimple on you butt (one woman did last night) why are you at an ER? Was it there yesterday befoer 5pm, most likely. Is it going to kill you before 8am? No, no it's not.
Also if only those with genuine "emergencies" use this survice, the average wait time would not be 3 hours just to be seen.
Sorry, I had to vent.
P.s. Do you not know how much an ER charges? It would be a heck of a lot cheaper to wait as well
