I've noticed an ad campaign from the Mayor of London on the tube which encourages people to recycle newspapers on the grounds that they block doors and cause delays.
I feel a Freedom of Information request coming on. How many recorded instances are there of newspapers causing delays on underground lines?
If it were real, it would have been used as an excuse in announcements. 'We apologise for the delay, ladies and gentleman. This has been caused by our inability to unwedge a Metro.'
