Japan visitors, you may have noticed we don't have a "tip culture" in Japan, as gratuities are built into the price. But, you can leave a "Japanese Tip", which is when a restaurant patron folds the paper chopstick holder into an origami figure. Waiter Yuki Tatsumi collected samples from around Japan, and you can see a gallery of some of them. One person's trash is truly another person's treasure. (via Japan Times)
