Returning on Investment After being away on buisness, Tim thought it would be nice to bring his wife a little gift. ""How about some perfume?"" he asked the cosmetics clerk. She showed him a bottle costing $50. ""That's a bit much,"" said Tim, so she returned with a smaller bottle for $30. ""That's still quite a bit,"" Tim complained. Growing annoyed, the clerk brought out a tiny $15 bottle. ""What I mean,"" said Tim, ""is I'd like to see something really cheap."" The clerk handed him a mirror.
