Minka Kelly proved too much for the "Charlie's Angels" crew member who got fired after slapping her ass last month -- he violated Rule 1 in the workplace ... look, but don't touch.  

As TMZ reported, Minka told the guy never to do it again, but ABC got wind of it and immediately 86'd the guy.

The pic (above) shows Minka outside David Letterman's show yesterday.
