Well Tami.......first of all these people are sick and are probably not in the best of moods anyway. Also, I would bet that those people at one time in their life ALSO paid taxes. If they are on medicare or medicad they probably paid taxes MUCH longer then you have.
I have experienced rude nurses who treat their patients with disrespect and a carefree attitude. Frankly your comment proves to me the lack of respect some nurses get is well deserved.
