Ewww... I hate them, no I loathe them, whichever is more intense, actually both !!
Imagine walking on the street, a moderately crowded one and suddenly you see a spurt of red spit out of the mouth of a person about to walk past you, and a red blotch on the street where you might have kept your next step.
I have, and I am really delighted and relieved to say this, never been a casualty under these circumstances. But I fear that someday, I or the spitter might decide to increase pace of walking, then... anyways, the spitters on a locomotive, mostly on a bike scare me more because their spit might fly in an undecided direction...
Use a sink, or toilet. Spitting in a dustbin is also disgusting.
I understand there's a need to spit, once in a while but as far as I can remember, the spitters I have seen casually spit on road while walking, as if spitting was like any other activity for them. No wonder Indian roads remain defaced.
At least think of those poor who sleep beside the road at night, think of the workers who clean the road and the pavements, think of that disgusting feeling you create in every onlooker's mind.
God is watching you non-sink spitters... and I'm sure He also doesn't like this behavior. :D
P.S. - Paan is the main reason for people to spit... have sweet paan, why to have tobacco paan and spit later! Get high on other drugs or smoke it instead! :P
