Did you ever think that it pleased the owners? Forget the smokers and the non-smokers — neither group which owns the business. Neither group put up the money and the sweat equity to open and keep going the business. What about what pleases THAT person.....the ONLY prson that counts in this equation.
We come right back to the main point here — I own the business, you do not have to come into my business, so why do you feel you have the right to tell me who my clientele should be even if you never intend to set foot in my business to begin with?
