We'd been wondering about the state of the dishcloth in the staff room (and/or the state of some of the meals people have been having): even though it's changed daily it's always grimy and grey when anyone comes to wash up. Today we find the reason why: one of the library assistants polishes her shoes with it.
"I need to clean my shoes when I come in. What else should I be using?"
Some days you can only wonder that the sickness record isn't even higher.
