A friend of mine borrowed a library book that I had taken out (I know, I know), I have been renewing it for five months, but now have to take it back as our degrees are finished, she says she returned it to the library, but doesn't have a receipt. The book is still outstanding on my account and the library are going to charge me £30 (cover price of the book to replace it).
AIBU to expect her to pay? (I have already covered about £6 in fines, but I figured they were kind of my fault as I could have renewed it online, but forget as the book wasn't actually in my possession).
