Ban all butts

David Mansford of Canterbury (NSW?) has sent in this letter to The Daily Telegraph:

The answer to our worst litter problem is simple: ban cigarette butts. Then the only litter that smokers leave behind would be a bit of papeer and a bit of tobacco (not a synthetic filter that lasts for decades). What possible objections would the smokers have? The risks to their health?

And speaking of rubbish - what do you do when you see someone drop rubbish on the street - right next to a garbage bin? Is there a proper etiquette for getting them to pick it up and bin it ... "Hey Tosser"?
