With the Northern Line escalators currently out of action at King’s Cross and passengers being diverted the long way round, there are lots of posters up on the platforms to say ‘This way..’ and take you to where you want to go.

Except that here, the arrow pointing to the right is odd, because visible to the left is the staircase that takes you up to the Piccadilly Line. If you follow the sign, it will take you at least five minutes to get to the Piccadilly platforms, however, if you take the stairs that you can see in the background of this photo, it will take you 30 seconds!
