Pole Hogs

Pole-hogs - you know who these people are. They're the numb-nuts on trains who hog the poles - the poles that are used by people standing up so that they don't fall down. Pole-hogs often lean their entire body against the pole, thereby restricting the amount of pole that is grabbable by others. Pole-hogs can also be characterised by the use of two hands (really, only one hand is necessary, isn't it?).
Pole-hogs are the bane of civilised public transportation. By reducing the amount of pole available for others to support themselves with, pole-hogs are simply being inconsiderate and rude.
I call on every public transport user to fight pole-hogs wherever they may appear! No more hogs! No more hogs! No more hogs!
