I went to use a photocopier in a different area and spotted a sarcastic message on somebody's desk about not going in the draws (sic). I left but felt drawn back into the room. I got my red pen out and hovered for a moment but managed to stop myself.
I returned later and saw the author, I pointed out that her message might be more effective if she spelt drawers correctly and spelt it for her.
"I'll just put in an apostrophe" she said, leaving it as 'draw's'.
What could I say?
