I'm typically very good at getting along with people, but I suppose my reaction to an asshole depends on the type of assholery being committed. Take for example someone who is egotistical and condescending. I may not necessarily like that person, but I can tolerate that person so long as the work being done is of good quality. On the other hand, take for example someone who takes credit for the work of others or in some other way actively seeks to step on his/her peers for personal gain. I have no tolerance for that.
