A friend looked after our pets (paid) while we were on holiday. We came home to find the freezer fully defrosted, she owned up to opening it and it clearly didn't close properly. Not sure exactly how much was lost but probably over £100. She's offering to pay but given she is a friend and it was an accident I'm leaning towards saying no. If it was a professional I'd probably think differently. I'm curious to know what others would do.
