I own stock in YUM, which is Pizza Hut, KFC, and Taco Bell. Repeatedly, the board of directors have refused to make their restaurants smoke-free citing that they comply to current regulations and doing so would put their restaurants at a disadvantage to other restaurants that allow it. Basically, it would hurt business.
Of course, I am disappointed that YUM has refused to become an industry leader but I also figure other restaurant chains use the same excuse. The solution is to create new legislation and regulations that put the companies on equal footing.
So we may need to be more vocal and active in encouraging out lawmaker in creating laws and regulations that make companies take care of the environment.
