Anonymous co-worker in your organisation. Possibly frozen in time from the 1980s and the toast of Wall Street. He’ll be ready to sleaze his way to the top, 80s style! He knows about business and has a tie. Also went to a lot of coke parties. The secret to his success is all about appearances. Outside of the office he goes back to the farm, shifts some paradigms and revolutionises outside the box. Liked the Safety Dance and died from Boneitis.
