I am not a smoker but I'm disgusted by PAP technocrats treating smokers like sub-humans.
Other than an indoor ban on smoking (which should be left to the business owners to decide), there should be no ban on any outdoor smoking. If it's air quality you're concerned about, joss paper and joss sticks are even worse offenders, but the PAP govt is chickenshit whenever religion is involved - any religion.
Maybe places like the Changi Jewel is bleeding money now, so they're trying to 'recoup' the money via frivolous fines.
