STICKY SPLINTERS - JAPAN

We're all familiar with the wooden chopsticks you get at Asian restaurants. They come stuck together, and you snap them apart which usually leaves a few stray splinters on the end. If this happens in Japan, holding the chopsticks between your palms and loudly clattering them together is a big insult to the waiter or sushi chef because it indicates that his utensils are cheap. Instead, rub one chopstick against the other gently.
