Common sense, something we'll likely never see here in the U.S., fewer smokers = millions in revenue lost, they'd never admit it, they want us smoking.
Well ... I'm currently sitting in one of the restaurant chains which probably has a "no smoking/vaping" policy.
But I'm vaping. The manager doesn't mind. The staff don't mind. So far, the customers haven't complained.
The USA is full of sensible people everywhere I go. (I'm visiting from Australia.)
But you're probably not referring to the average American. Rather, the "powers that be".
Still .... I thought I'd highlight this issue because I love the USA.
