As someone with poor health who's prone to unexpected trips to the ER quite often, I've always noticed that there are way too many people who are not in an emergency. Most are there because their baby won't stop drooling or sneezed a couple of times prompting a panic attack. Others are just there doing general GP stuff - getting prescription, checking test results, etc.
This has always been a big problem and now even more so due the pandemic. Why do it?
EDIT so it seems most people condone going to the ER anytime you are worried because that's what triage is for. Please note that filling the waiting room with non emergencies increases the time it takes for a nurse to triage a real emergency, or could even contribute to the ongoing stress of these people. To each their own but I dont condone this.
Don't judge parents with babies. Babies can go downhill very suddenly, and something that just looks like a fever can be life threatening (eg meningicoccal). The parents may have rung a 24 hour advice line and been told to go into emergency - you don't know.
Also just because you can't see blood spurting out of someone doesn't mean they may not be experiencing a life threatening condition or illness.
Everyone else must be allowed to be there or else they wouldn't be. Eg getting test results - obviously they've been told to go there to get them.
Emergency patients are triaged so you don't have to worry about waiting in a queue if you're having a heart attack.
I think you need to take off your judgey pants and put them away.
