There is a time in everything, including how to insure smoke free restaurants.

Apparently welcome in most cities in the world, it is not working in Beijing, China.

Customers desert smoke-free restaurant

BEIJING (Reuters) - Beijing’s first smoke-free restaurant chain faces going out of business after its customers deserted it in droves after the ban was enforced, state media reported on Friday.

The Chinese are the world’s most enthusiastic smokers, with a growing market of more than 350 million, making it a magnet for cigarette companies and a focus of international health concerns.

Beijing authorities had written to 30,000 restaurants asking them to
put smoking bans in place, but not a single one had taken up the
suggestion, the paper said.
