I'm not sure which of these annoys me more:
a) Bland knee-jerk-reacting dullards who whine on and on about the Nanny state and throw their toys out of the pram whenever politicans try to intervene to improve people's health or lives.
b) The idiots who've helped confirm a)'s predjudices by putting signs up on the tube telling us the correct way to use an escalator. Turns out we can hold the handrail and we shouldn't run.
Now we know.
