ER patients are NOT served on a "first-come first-served basis" but, surved on the current severity of their issues.
As mentioned before, this is a common ER issue. You can check other nearby ER for wait times (some even have apps) to get an idea if you could get more immediate care elsewhere. Most problems can be assisted at an Urgent Care center or sometimes even a nurse phone call.
That's how all hospital ER's are. Not just this hospital.
