Morning Tube Morons

What is it about using the London Underground that turns people into psychopathic morons?

I hate getting the tube in the morning as it's always so dangerously overcrowded. I travel between Victoria and Oxford Circus, two of the busiest stations on the network. The station and platforms regularly close due to overcrowding, leaving huge masses (I can't call them queues) of people waiting at the ticket gates or outside the station.

Today I was with a friend who hates getting the bus, so I tried to catch the tube with her instead. Whilst in the mass of people at the ticket barriers, a fat middle aged man with short grey hair, grey fleece and large holdall pushed in front of me and painfully elbowed me in the ribs at the gate. The other side I saw him push other people out of the way, and my friend said he had also shoved her.

So what is it that makes people want to behave like that? I'm sure they wouldn't do it anywhere else. Maybe it's just the sheer weight of people crowded down there that makes some people just go a bit stir crazy. The odd thing is, going the other way in the evening, everyone is really polite and considerate.

Anyway, back to the 73 bus tomorrow I think. It's far more civilised.
