If someone comes in thinking they have a stomach virus...and it's a perforated intestine...there's not much an urgent care center can do for you. Same thing for chest pains that turn out to be a heart attack and a stitch in the side that turns out to be a ruptured appendix.
It even works that way in hospitals. When I worked at the hospital, they were required to transport patients from the same-day surgery center to the hospital by ambulance.....all 100 feet or so of the trip, even though the surgery center was connected to the hospital by an enclosed "bridge" across the driveway that separated the two. Instead of the two minutes it would take to push the gurney across the bridge, the patient had to be taken down to the ground level, loaded in an ambulance, driven 20 seconds to the emergency entrance and unloaded from the ambulance. Didn't make any sense to me... Few things do anymore. I can tell you, when I'm elected God, there are going to be some changes made around here!
