I used to do some work for an Architectural and Engineering practise that was owed by two blokes who were mates, one an Engineer the other an Architect.
They used to make me laugh because the Architect would come up with some design that he wanted to do, but his mate wouldn't let him because it was structurally unsound, and to make it so it was ok the Architect thought it was then ugly.
They would then retire to their respective corners of the office with the Architect muttering he hated engineers and the Engineer muttering about stupid architects.
They had worked together for years so I gathered this procedure to get a design out the door was the regular daily occurrence.
