"no one forced any non smoker to enter a smoking environment."

Same old shit! Nor did they provide an alternative excepto say if you don't like it you can drink at home. There was plenty of oppotunity to do so ( 300 or 400 years, I reckon) but chose to wait for it to be legislated on and you know what happens when new legislation is brought in - it's always OTT. And those people who went home to drink in a non-smoking environment are still in the habit of doing so and you know how hard habits are to give up don't you?

But in the end it's the staff who are being protected not the non-smokers.
