I get the opposite, always the dps or the healer that's being rude. Dps runs ahead and aggros, it's the tanks fault for obviously not being fast enough to pick up their impatience, etc; etc.
I'm pretty calm and patient, and will try to pick up mistakes either I, or someone in the group makes, but will just drop out at the first sign of douchyness, saves a ton of time and frustration of dealing with those kinds of people.
