Spitting.
I find it SO disgusting. Most often notice footballers doing it but just driving through the beautiful Highlands of Scotland and a passenger in the car in front leaned his head out of the window to spit a huge glob which flew back and almost hit our windscreen causing a collective "ewwwww" in our car.
It always seems to be men of a certain type doing it... are there any spitters out there brave enough to shed some light on this horrid habit?
AIBU unreasonable to find it so offensive?
