Today May 19th at post conference Amanda was very disrespectful and rude to me, She was arguing the fact that she did not get lunch today . We left clinical at 12;15 today because of a meeting at the school for full time instructors. I told everyone in my group to take a coffee break earlier because of the dismissal. She did not take one for whatever reason. She then proceeded to tell me that the 3rd floor students took one in which I replied that is not so because I went on a break with the 3rd floor instructor and she said she was not giving a lunch either since we were getting out early.My concern is Amanda could only know or assume that is if she was using her phone in clinical to text someone on that floor. I responded by telling her I don\'t care what other clinical groups do this is our group and I will do what I feel necessary. I then proceeded to just dismiss the group. One of the staff nurses came to me and said I can not believe the way she spoke to you. If I did that in clinical I would have been thrown out.
