The obligation to treat patients who are in need in an emergency setting IS a legal obligation in the US. If a patient is refused treatment at an emergency room, both the doctor and hospital can get gigantic fines. I don’t remember the max off hand, but it’s somewhere along the lines of $50,000 and $1.5 million, respectively. The law in question is EMTALA, or the emergency medical treatment and active labor act. A patient must receive stabilizing treatment, or be stabilized to the best of the hospital’s ability and transferred to appropriate care.
I’ve made an exception once or twice for a logo that actually looks good. I think that is, considering how many pieces of clothing I’ve seen and not chosen, something like a one-in-a-million chance.
