i found some must-know thing. if you leave strip after dealing with benny, but without meeting that ncr soldier (who gives you the ambassador's note), you will be an enemy of ncr. i made my way through strip swinging my fists (because i didn't want to start a conversation with him), but as soon as i left it, i found myself declared as a terrorist (thus i will be shot on sight, which is pretty damn bad).
