As an aside, on the subject of waitstaff in restaurants, when I was in Oz visiting family, I noticed that while in the coastal cities I saw a broad range of faces in a broad range of situations, but once I was a few hundred miles inland, the only non-white faces I saw were serving me food; they certainly weren't students.
