Whilst my initial experience involved the lavatory use habits of Marines traveling in the Troop Deck of an LST (a "Large Slow Target" with a flat bottom and the rolling and pitching habits of an overweight wrestler attempting to escape a submission hold), we finally agreed to allow some use of the Officers' Head in exchange for the alternative, not using the heads at all, which creates a terrible clean up problem for the ship's crew.

It's not an issue with which to take great issue, especially when the beverage carts block the Y aisle. Of course, I do base a part of my response in having traveled aboard the infamous "Stretch 8", a prolonged version of the old DC-8, in which the after lavs were at least a quarter mile from the bulkhead, too far to walk and wait for any but the youngest of prostates.
