I have two friends who have the following disagreement:
One friend worked for the other as a gardener. Let's call the gardener Bret. Let's call the other friend, John. One day, while Bret the gardener was working at John's house doing the gardening and landscaping, he left the hose on. It was not running water, though. The faucet was simply open but the hose's handgun at the end of the hose was closed.
That night, something happened and the faucet blew off and allowed a lot of water to run out. John is afraid that he is going to get an $800 water bill next month and wants Bret to pay for it or part of it. Bret does not feel responsible because he feels that is a malfunction of the house and, therefore, not his fault. Hose faucets in a garden do not normally "blow off" and spill a bunch of water.
My questions are: What is a fair solution to this disagreement? Is Bret even responsible in the first place? If so, is he 100% responsible? Should there be any restitution and if so, how much?
