Rules of the game

I wonder if I'll ever understand commuters' mentality. The insular disposition that people adopt on a tube train is reflected in their complete disregard for what anyone else is doing. I am — admittedly — a demanding person. But why do people fart-arse around so much when they catch the tube? Are they being deliberately obstroperous or does their idiotic selfishness come naturally?
Example: today at King's Cross only one ticket barrier was open on a particular exit; consequence, twenty-odd people in the queue. When it comes to my turn to go through someone barges me out of the way, only to find that he doesn't know how to insert his ticket properly and holds the entire queue up. Was he a wanker or just a plain knob?
Escalators carry a sign saying "stand on the right". It does not add "and take up as much room as possible making sure to elbow or handbag whoever passes you". Nor does it say "stand on the right and dawdle on the left". If you're trotting along really slowly, why force others to go around you? Do you drive at 50 mph in the middle lane on a motorway? Probably. And when you get to the end of the escalator, do you then decide to stand around blocking off anyone else trying to get off it?
On reaching the platform everyone seems to think that the least crowded carriage is the one that's closest to the platform entrance. No need to move along. Unless of course you see a particularly fascinating poster advertising online gambling, which causes you to hover in the centre of the platform forcing anyone who's got past the platform entrance brigade to tightrope walk along the platform edge.
Then try to board the train. Standing by the door is clearly the most comfortable place to be. Don't these dickheads realise that at every stop people will have to clamber over them? Are they just stood there for the cheap thrills, a crafty brush against a frazzled fellow passenger? Or must they stand by the door so that at all costs they're onto the platform first at their stop, to amble up the centre of the corridors and turn the left-hand side of the escalator to treacle once more?
It's all I can do sometimes to hold in all the abuse I want to hurl at these miserable idiots. At least this blog entry was cathartic.
