Yellow box for smokers

[tom]

From coffeeshops to cyberspace, you can almost see the smoke rising. Those who insist on puffing at food courts and hawker centres are locked in a turf war with non-smokers put off by the habit.

At the MRT stations, we are always reminded not to go beyond the yellow lines . In the coffee shops, smokers are asked to stay in the yellow boxes.  Anybody knows why always YELLOW ? Who is the genius who suggested the yellow box ? Surely end-up the smokers and the non-smokers will be at loggerheads.

Vehicles are asked to keep off the Yellow Box ! haha...

Even in army, the big big parade square is the biggest Yellow Box.
