The state of spitting is little better in our cities. Discarded gum is the white noise of a pedestrian's commute. Walk enough in the CBD and most of us get to the point where we don't even notice those little grey splats any more.
In the United Kingdom, inner-city chud-spatter is now so prolific Jamie Oliver has taken a stand.
He has suggested a Singapore-style ban on everything Wrigleys and otherwise.
Can you imagine a black market where drug dealers diversify into selling cartons of Airwaves instead? I suppose anyone lunching at Jamie's Italian will just have to hope they provide a bowl of mints by the till.
As a chewer from way back, I'd place a chewing gum ban only slightly behind the flag debate on the list of current political priorities. It's a scourge, sure, but it's hardly Ebola.
So, instead of a ban I'm suggesting an advertising campaign based on the little-known philosophy of a former minty-fresh girlfriend who, shortly after spitting her gum out a window, had to cut a glob of discarded Hubba Bubba from her hair.
Beware chewing gum karma: "If you don't bin it, you'll soon sit in it."
Or, in extreme cases of selfish spitting, for those hawking into Lake Wakatipu, we'll craft you a pair of my brother's famous sunglasses to change your view.
