sushi etiquette

This chart seems to be causing a bit of a controversy around the web but I really like the illustration style.
I'll include one comment: "I’m Japanese. I think these are great and accurate advices.
You can eat the way you want to, but just try these when you eat Sushi in Japan. I think it shows that you respect the culture.
The Sushi chef will love you and may give you extra Sashimi. I would love to learn how to eat that huge humburger I had when I was at a restaurant in California. " - 日本人
