The only thing "regrettable" is that he got caught on camera. This is perhaps the best -- and smartest -- collection of commentary on the episode.
I don't smoke anymore but god damnit it pisses me off when governments tell business owners they can't allow smokers anymore. (Which my city council did here in Ames some years back. I never had any problem with places where lots of people smoked.
Or, rather, I solved the problem: I just didn't GO to them. Problem solved....)
As I said to the city council when it contemplated this ordinance, which it did on grounds of "public health": What's next? Someone's gonna complain that they're allergic to grass and so you're gonna pave over all the public parks so that he/she won't suffer the "health" consequences of living in a town with grass?
