After reading about that case, I have little sympathy for someone who would put themselves in that position. BTW, as far as I know, the doctrine of "Last Clear Chance" does not apply in every state.

Anyhow, when I see something I don't feel I can keep quiet about, I tell the customer & if they don't want it fixed, I make sure to put a description of the problem on their invoice.
