Pushed or nudged - will we end up better and thinner?
I was once berated by an official in Toronto airport, who kept gesticulating at my glass of beer and a blue line painted on the lounge floor. I gathered eventually that it was forbidden to drink on the wrong side of the line.
Now that's what they call regulation. A blanket ban, no exceptions permitted, and a fine for disobeying - although in this case he let the hapless Irishman off with a glare.
Such regulation is a bit out of fashion, though. The modern method might involve charging extra to have a drink on the other side of the line; or making the seats more comfortable on the drinking side; or just putting up signs asking customers to drink on that side, and perhaps pointing out some good reasons why they should (although I could see none).
