Look, if your going to fight with somebody at work, make sure it's not the supervisor. And, when I say fight I mean a very heated argument. And, the other rule would be do not argue with a co-worker in front of a customer. Yeah, not a good look for sure...
I've never understood job references. I want the job. Not my friend, not my relative, not my past co-workers. So, your going to rely on someone else to help influence whether I get this job? Kind of crazy. LOL A simple interview with me should give you a lot of information...
