Now it is clear why we are fighting against the concept of "service" in medicine? A little more and we'll get to it. If you don't pay attention to the Ukrainian Russophobia, then the service is what it says. The service provider (in this case, a health worker) may refuse to provide services. All kinds of Hippocratic oaths and other morals are not taken into account: if you do not meet certain criteria, goodbye, service is refused.
