Here in LA smoking is already banned in bars, restaurants, etc.
I really like it. It helped me quit, because I used to smoke a lot in bars just for the heck of it. Now, I don't feel the pressure to smoke in a bar because it's not allowed.
Restaurants- It's a whole new experience eating your food without the smoke from the next booth over coming into your space.
Go smoke outside. I would consider, especially after living in LA, that if someone were to light up next to me in a bar, they might as well have just let a stinky fart.
