I've never met a Japanese smoking Nazi here in Japan. I appreciate how tolerant Japanese can be. Even though I smoke a pack a week, I still think there is room for some criticism of the lack of smoking etiquette. I wrote earlier about my first rule.
Rule #1. No smoking in the car with your kids inside. I don't care if the window is down. Now, I have a second rule.
Rule#2. Do not discard you cig butts in the park. You fools think of the children. Sure, have a smoke but be considerate and stay away from my kid and clean up after yourself.
