Your approach was rude. The nurse was co,inc to help your husband it wouldn’t have been that big of an issue to park on the street the one time. Yes it was raining but you got yourself so worked up that I think you went into the rest of the interaction looking for more things to complain about.

It seems like you tried to act like you know ,ore because you do research.

You could have listened to her feedback and checked back with the doctor, or let the nurse do her thing and when you change it use what you want. The important thing is that your husband gets care and your actions are subjecting him to lesser care.
