When you go to a Japanese restaurant you see people rubbing disposable chopsticks to remove splinters. I have never seen that done in Japan. After a bit of research, this is what I’ve found out:

Q. Am I supposed to rub my chopsticks together before my meal?

A. Some think that rubbing your chopsticks together before a meal is a Japanese custom meant to remove splinters. In fact, rubbing chopsticks together can encourage more splinters than it actually takes off! This ritual originates from an early Charlie Chaplin movie that was popular in Japan before WWII. In this movie, Charlie Chaplin rubs his knife and fork together as a gesture of culinary anticipation. The Japanese people who were fans of the movie at the time, mimicked this action with their chopsticks. After WWII, American GIs returning from Japan brought this American born custom home again! In Japan today it is not a commonly practiced custom.

As for me, I don’t do it. Unless you are cool like Harrison Ford in Blade Runner.

I am sure this will benefit the corporation America greatly (on cost saving), but at least that’s something anyone (with a computer) can do to try help out the environment.

Not sure the site LifeHacker got some tips or tricks like this.
