Smoking in restaurants is, was, and always will be stupid, dangerous, unhealthy, and inconsiderate. The OP's example is on our route to and from Ottawa and Kingston, maybe I'll check it out...or not.

(Aside...As much as I loved my parents, I always resented their smoking. They both managed to quit before they retired, but long after I'd left home.

As much as I loved playing regular pub gigs, by 23 I couldn't take the smoke anymore and quit gigging for several years and didn't gig in pubs again until the smoking bans started. I resented that too, it forced me to other work I didn't enjoy as much.

When I started working (I got a county job with a decent income and great benefits, for the time) it was mostly to shore up my music income. Working in county offices and buildings the county leased to the province, one of my security/maintenance duties was to clean out ashtrays and dispose of the contents safely. Besides that the air was rank because everyone smoked, I had to clean up after the smokers. The only blessing was part way through my shift the buildings were empty except for me, so it wasn't AS rank later in the day.

It was impossible to escape.

A parent of one of my guitar students (I've been teaching music privately for 14 years) said they were going outside for a smoke. I told them to go out on the street, it's not allowed on my property. Says who? Says me. A teenage student asked me if he could smoke during the lesson, as he was putting it in his mouth. Well, of course not. It seems he was allowed to smoke at home.

It's still out there. My wife, as part of her job, has had to keep an eye on a school smoking area from afar. It's off school grounds nowadays, but only across the street. When I went to school, smoking was allowed at high school dances. Some progress in 30 years I suppose.)

Peace, Mooh.
