Here we go again. A whiff of a new virus and the public health nannies are back waving their face masks like shrouds and treating us like a bunch of kids. I wouldn't mind so much if there was any logic to it but there ain't.

I mean, if it's now the law to wear a mask on trains how come half the passengers still don't bother and why don't the ticket staff tell 'em off instead of lounging about the barriers being jobsworths?
