I will admit to being a little sensitive like the thread starter. I would have probably been upset too, not because of a bottle, because of how I was spoken to in this situation. As a new nurse myself, we have some senior staff on the floor who are plain rude. Anytime you ask them questions they look at you like you are stupid. It does affect your confidence. Once you are at the end of your shift, a little tired and stressed from a hard days work, things affect you differently than they would if you were at the top of your game.
