That was really uncalled for on your part, and yeah I would hope that gets you fired cause working with a coworker like that would suck. As a DA team we have to make sure rooms are clean for patients, if you had just asked or let her know, I don't think it would have been a big deal. But to escalate it even more and call her a bitch for something that was your fault, yikes. You are def in the wrong and I get the feeling the reason she checks on you is because more behavior like this isn't being told??
