CC was telling me about a friend of his that had his office located next to the men's restroom. Obviously, the contractors for this particular building were not blessed with forethought. In order to save money, they connected both the guy's office and the bathroom to the same ventilation system. This opened a direct conduit between his office and the "delightful" aromas of the men's restroom.
Needless to say, the guy was known to take long walks right after lunch.
