I got another story:
A few weeks ago, I was doing the read reaper with a friend. I go around killing things at the entrance. When I get at low health, I yell for a heal. I get none, then I die. When I revived, I saw the healer standing doing nothing. I said "I said heal, dammit!". He says he was healing the tank (my friend tjeagle who was doing perfectly well herself, plus he was not healing anyone). So he starts ranting and being an ***, so we boot him.
