I noticed a sign at Heathrow that read as follows:

“At shift’s end and prior to departing, employees will check that all 310 doors are closed and locked.”

I’d be curious as to if and how anyone has ever accomplished this task.

Yes, upon rereading it I did get it. So here’s a challenge for all you writers out there. How would you rewrite this notice to ensure clarity and understanding?

Also, this should cause us to reflect on whether the instructions we proposal people send out to our respective teams are clear and easy to understanding.
