Try spending a night in 11A Club World and having "visitors" clomping past all night back and forth to the toilets (or to steal the food from the Club World kitchen when the cabin crew backs are turned), women smashing you in the arm and head with their huge handbags while you are trying to sleep. That focuses the mind on why people who shouldn't be there need to stay in their own cabins.
11A is a window seat on any aircraft... not sure how these women are smashing you in the head with their handbags, unless of course you are going to LOS where the bags are indeed large and could concievably be hitting both you and the aisle passenger?
