I once had a Vice President explain to me the rules at the bank he worked for. A person of level X was entitled to an office and one piece of art. A person of level X+1 was entitled to an outer office and two pieces of art, and so on.
When he started telling the story, I assumed he was pulling my leg. Once he got about three levels in and had clear details on all the differences, I realized (sadly) that he wasn't kidding.
