Restaurant goers and bar hoppers may have clearer lungs, but some businesses say their customers have cleared. Restaurant and bar owners say their clientele dropped anywhere from 30 to 50 percent last year.

Booches, usually famous for its pool tables and pint-sized hamburgers, now has a new fixture. It's a framed newspaper article showing the officials who voted on Columbia's smoking ban - and based on their vote - if they're welcome in the business.

"Two ladies who worked for the city said, 'You know, we used to come in a lot, and we'd have a smoke and sit down and have a few cocktails. Now we just stay at home - but we have more money to buy shoes.' I was like thanks, darwin," said Richard Robertson, Booches co-owner.

Booches isn't the only business hurting from the law. Since the city of Columbia enforced the smoking ban, seven local businesses have closed their doors, citing the ban as at least one of the causes, according to the boone liberty coalition. Cody's Saloon- a 19,000 square foot country dance bar, says it lost about half the patrons it had a year ago. The owner says she blames the smoking ban for independent restaurants and bars shutting down.

"There won't be any, I guess you'd call them ma and pop-type establishments left. Because it'll all be corporations because they're the only ones who have the pockets deep enough to keep going," explained Becky Reynolds, Cody's Saloon owner. And Reynolds says smokers who do come to the bar don't spend as much.

"They're having to walk outside so we're losing revenue in that instance also, because they're not inside drinking. Because they're having to go outside to smoke," said Reynolds. She says before the ban, she had drinkers and dancers come from as far as Kansas City.

The Boone Liberty Coalition asked the city council to repeal the ban last month, but some restaurants and bars say they've lost hope for any type of smoking ban reversal.
