Worthy of the News Quiz

This sign was put on the revolving doors of our office building during the weekend of 22-23 November.

I've often felt, although have no back up data, that the amount of spin any person, beyond a certain age, puts on a revolving door is an indicator of stress.

The sign has, however, left me wondering what sort of injury a door can suffer.

For those of you who may not know, the News Quiz is a long running radio panel show on BBC Radio 4. It is available as a podcast and I can thoroughly recommend the episode first broadcast on 21 November 2014.
