What you apparently don't know about this situation is that a couple of years ago, the city of Madison required bars and restaurants that wanted to allow smoking to put in expensive separate air handling systems. Many did so, acting in good faith, and investing in some cases well into six figures to provide separate, oversized ventilation systems for smoking sections.
The city of Madison rewarded their adherence to the law by outlawing all smoking in bars and restaurants, despite the investment on the part of business owners. The resulting reduction in the value of their investment constitutes a "taking" of their property. It's morally wrong, and constitutionally questionable.
And, before you ask, no I am not a smoker, and I prefer to patronize businesses that are not filled with smoke. However, I do not have the right to impose that preference on the private property of someone else.
Thank you for that post, Applause!
Very well said, LouD. That sums up the situation perfectly. Thank you! :)
