Had the same experience last Thursday.
Friend injured himself and dilly-dallied to the last moment before seeking medical assistance. As a result, all the urgent care clinics were closed and so he asked me to drive him to the ER at the local hospital.
We walked in there and quickly realized that (a) most of the people there were complaining about things covid-related, (b) most of them were, for all intents and purposes, apparently asymptomatic, and (c) the hospital had closed off half of its ER waiting room for some other purpose, and was jamming people together like sardines - forget about social distancing - to the point where it seemed like the ER was the place to go to GET covid, not the place to go to get a cure or a therapy for it. The last straw was when the triage nurse finished getting the all-important insurance info, and then directed my friend to sit next to one of the few people who actually did seem to be suffering from covid symptoms (he looked miserable and was periodically coughing). At that point, my friend decided that he could manage through the night and could wait for the urgent care clinics to open in the morning.
Meanwhile, there were a total of three - count 'em, three - hospital staff there. If that ER was overloaded, it was because of the conscious understaffing and asymptomatics who should have been sitting at home getting their vitamin levels up and resting, but who had instead been fear-proned into thinking they were going to die because of a technical positive test result; it wasn't because of some actual pandemic of sick/unvaccinated people.
