Let's assume it was an innocent remark i.e. the nurse simply meant that she didn't want to be treating him professionally.

Would you fire a waitress who told a customer "I hope you never come back?" If the waitress can't deal with the one aspect of her job which is to treat customers professionally -- maybe the waitress should look for another job.

Or what if you got into an accident with a firefighter who said "I hope I never see you outside a burning house (while on duty)" (which I think is closer in implication to what the nurse said). Would you take that as a threat?
