well, just because those people would go out doesn't necessarily imply that the business would do just as well if they also lost some of their smoking customers ... but i also know quite a few people who won't go out to places where there is smoking. imho, it is much nicer not to be subjected to it and i do shy away from places that are bad. not that i agree with making it a government-induced ban, but to the business owners who make the choice for themselves. it so sucks to go home and smell like you've spent a week cooped up in a coffin full of cigarette smoke. btw, any such ban should include the area outside of the entryways.
