Once again, London Underground has left stations unstaffed, and once again there have been potentially-dire consequences.
On Friday evening, Chigwell station was left with no staff, and there was an attempted robbery of the ticket office. When staff from other stations responded to the alarm and the police attended, they found physical evidence of an attempt to break down the door.
The company will probably complain that no harm was done! But staff had to leave another station to deal with the incident. And future attempts at robbery may be successful - and may have disastrous consequences for any witnesses.
