I was just leaving the pottery studio earlier today and saw this smoking zone.
To be honest, it is not the first time I see it, rather, the first time I bother to take a photo of it...
Out in the sun, a rectangle, measured something like 1x1 meters (3x3 feet), mark the smoking zone, making sure that if the smoking doesn't kill you, then the sun will do the job.
Starbucks had cancelled long ago it's smoking zones. Coffee Beans dedicated 3-4 tables for smokers, luckily under the parasols, attracting a crowd of the nicotine addicts, who are waiting to conquer the rare seats. Just a handful for other coffee shops still have a small place for smokers, making them a smokers heaven (some would say - hell...)
If you are a smoker, you probably feel like the animals in the forest which are been slashed, diminishing your living zones. In time the only place you will be able to smoke in will be your home, though if you live in the US, not even that.
If you are not a smoker, don't start! It is foolish!!!
