Way to complicate something that isn't

A New York City video store called Kim's categorizes its movie collection alphabetically by director's last name. Great idea, right? You can't just walk in and locate, say, "Blue Valentine" on the shelf; instead, you have to ask a staff member who directed "Blue Valentine," and then wait for said staff member to look it up on their computer (because, most of the time, they don't know who directed the damn movie either. I'm not criticizing them; no one in their right mind would expect anyone to know off the top of their head who directed every movie in the store. Oh wait...) and point you to "US Directors, Derek Cianfrance." That's right: just when you thought it couldn't get any stupider, you're in for a surprise: movies are also categorized geographically according to the nationality of the director. Let's say you're looking for "Dangerous Liaisons." In order to locate it without having to waste time asking people and waiting for them to ask their computers, not only do you have to know it was directed by Stephen Frears, but also that Stephen Frears happens to be British, which means that the damn thing is filed under "UK Directors." Even though it's a Hollywood movie, made in America, funded by American producers, with American cast.
