I have a coworker that is really arrogant. She is the lab supervisor, and some of the people in the lab think she is so great (or at least act like they do). She says anyone over about 130 lbs. is fat (I am not exaggerating, she actually said 130), and she hates fat people. She also hates anyone who is in her opinion "stupid" - which means anyone who doesn't know as much as her or anyone who makes a mistake. She does not like mistakes, and in her opinion she does not make any. She makes comments constantly about people. I have been wanting to vent about her for so long!
