That's one that's not mentioned and really hard to deal with. Found common in startups, the Hurricane Boss is a brutiful combination of all of the above, cranked up to eleven.
I had one, a precocious Frenchman, who once walked back to my team's area, clapped his hands (in a way only a precocious Frenchman can), and commanded, "I want rounded corners and dropshadows. On everything." And then left. Fifteen nerds stopped dead in their tracks, concentration broken, pulled out of the zone. For rounded corners and dropshadows.
I moved my team as far away from the windows as possible as that was where he liked to loiter, but I never could protect them from the Hurricane. Productivity? Focus? Not here, my friend.
