One of the greatest "helps" a person can provide in any cooperative setting is upholding appropriate chains of communication. People don't realize how much they contribute to conflict or miscommunication by not requiring people to talk to the person responsible for or directly involved in the situation. I'm sure they think they are "helping" by stepping in themselves (although, boy, some are just trying to be the "savior"), but I'd say that it solves nothing and, in fact, increases the drama about 90% of the time.
What a waste of time!
It's one of my biggest pet peeves actually. Can you tell? Hehe. ;)
