I can assure you if you come via an ambulance you will get pushed to the front of the line over a walk in.
Easy to triage things gun shots are not so easy when the problems are internal. Easy to introduce bias. Parent poster thinks homeless and poor are only there because its warm or they have nothing better to do. It's okay to keep them waiting over someone who looks rich. They must have a serious problem, look at how well dressed they are.
