To be fair emergencies take many different forms. Like for example I had 2 bad infections one time when I went to the hospital and I barley had much pain & no fever, so I was treated as I was fine but after tests were done the doctors were freaked out lol. So the er should try their best to treat everyone accordingly if possible but we dont live in perfect world I guess.

But I agree no one wants to deal with the er unless they have to. Unless they are hobos for some reasons lol
