The worse case I ever saw of spitting, was a young girl standing at a bus stop with two children, the children were round about the age of 5 to 7, she spat in front of them, and others standing at the stop.
well the worse I heard - thank God - I didn't see - my sister was saying her neighbour's son over 30 years old - queuing up behind a funeral hearse and emptying his nose on the road.
