Watched How To Eat Sushi The Right Way from VICE | YouTube

Coming to you straight from the sushi chef's mouth, MUNCHIES presents the dos and don'ts of eating sushi, as taught by Tokyo's Naomichi Yasuda. Be warned: You've been doing it wrong. Just remember: It's okay to use your fingers to eat cut sushi rolls. Don't combine ginger and sushi, or ginger and soy sauce. Ginger is a palate cleanser in between bites. When dipping sushi into soy sauce, dip fish-side down. Never shake soy sauce off of sushi. That's like shaking your wanker in public.

I thought there might be some more subtlety here, but generally I’ve apparently been doing alright.
