So, what are the laws in Japan regarding restaurants and them accompanying people with dietary restrictions? I know that I said uneaten McDonald's is biofuel, but about ramen, is it necessary to always produce MORE PORK BROTH and KILL MORE PIGS just because it's okay that people don't finish their ramen because it's good biofuel? Should a certain ramen restaurant that forbade me from a kid's size ramen "call the superiors" about the rights of animals to not be unnecessairly killed for biofuel that could be easily replaced by clockwork, compressed air or mechanical computers like McDonald's ordering kiosks?
