Nichtraucherschutzgesetz

Should a restaurant allow smoking or not? I have no idea. Neither do
you. Who does? The restaurant owner. The restaurant owner knows that if
he bans smoking, he will get more business from non-smokers and less
business from smokers. He also knows that if he doesn't ban smoking, he
will get more business from smokers and less from non-smokers. He will
make that tradeoff and, if he has no particular interest one way or the
other, will likely do so in a way that maximizes his net income from
running a restaurant.
