What about the inverse problem? If you go to McDonalds and drop a glass pf coke, can auto-Ronald sue you to get back the cost of the cleaning?
2. McDonalds could make it so to get inside you have to agree to arbitration of any disputes. That's usually just used by companies to make you use arbitration instead of the courts when you have a complaint, but offhand I can't think of any reason they couldn't require arbitration in the other direction.
