No, nurses are expected and required to accept every patient as they are and provide the best service they can regardless of the patients druthers. While I think the entire fiasco is a nonsense, if she can't provide an unbiased service for every patient, she should consider if she is in the right trade. Whatever her personal opinions of that patient, she should have kept them to herself within his hearing. In this situation, she is the author of her own misfortune.
