You have (soon to be had) the option to sit in the nonsmoking area if you don't like it. I can't request a seat in the non hippo urine smelling area. But I can see your point, smoking offends you so it's evil, as you sit at the diner counter passing gas, but since it doesn't offend you and it makes you feel good it's OK.
Incidently, I frequent eating establishments that don't offer the option to smoke, it's their business choice and I can respect that. Many meals have been spoiled in those place the LePews.
