From the Avengers Case Files of Phil Coulson: Grocery shopping is necessary, Tony's a little too proud of his tech, Captain America's lost on the streets of New York, and sometimes social injustice just happens. Phil Coulson's the one who's got to write this nonsense up, and he is not their PR Manager.

Steve takes things like personal responsibility and respect seriously. Tony's got people he pays to take care of that kind of thing, and anyway, he's pretty sure that he's going to die of some exotic disease in his workshop, because Dummy's still a little spotty about what is 'clean' enough to put on an open wound. The rest of the Avengers are in this for personal gain, except for Clint, he just enjoys being a dick. And some things shouldn't be a chore.
