One of the more vocal bar owners against the smoking ban in Delaware was the owner of a bar that had gone smoke free on its own. He didn't want to lose the niche market/clientele he had created for himself.
The ones that truly annoy me are the ones who claim their customers would prefer non-smoking, but they would lose too much business if they went non-smoking, so they want everyone to be the same.
Just wait, this gym is going to be targeted as being discriminatory and they will be forced to change the policy.
In Michigan, the casinos lobbied for the smoking ban which they got an exemption from.
