In Japan it’s a common practice to rub very cheap waribashi (wooden chopsticks that you need to break apart) together in order to smooth them out and remove splinters. As such, it is considered offensive to do so when offered good quality waribashi in someone’s home as it indicates you think the chopsticks are cheap, and therefore it is an insult.
