No doubt about it, this area is a can of worms (with teeth).

Anybody know a lawyer who would be willing to make some general comments?

Personally, keep your hands off, notify the customer, if they refuse to fix it, make sure you note it on their invoice so there will be a record that at least you notified them. Don't know what I'd do if there was a housefull of kids involved, hope I'm never in that position.


Few things are harder to put up with than the annoyance of a good example.
