This sounds remarkably like how the squeegee men operate in a big city. Oh, hey, I just washed your windshield, you owe me some money. No? Oops, terribly sorry about that scratch as I walked by.
Except the squeegee men offer a service that you don't really need, and doesn't offer you much value. Responsible disclosure to a company is often much more important than a clean windshield is to you.
