Daisy is doing her nut: she's just back from leave today and she's found that nobody's done the cashing up at Dutch Bend while she was away. She's spent most of the day doing it and she can't reconcile it: it's just over ten quid adrift.
"I'm going to get a bollocking and a half off T.Aldous for this."
"Can't you say that you were on leave that week?"
Apparently that alibi only holds for Chief Librarians.
