Is it good or bad to set up smoking and non-smoking areas in hotel restaurants?

Good: it's respect for non-smokers, because after all, not everyone wants to smoke other people's second-hand smoke, which is n times more harmful than smoking! The same is spending money, why should we smoke other people's second-hand smoke? Then the whole dining environment can be better. Bad: some smokers may be driven away. If a family comes to dinner, some may smoke and some may not smoke, so they can't sit separately.
