Wait, denied because of pre-existing wear is crazy! So they came out, poked around your roof, and somehow that gave your insurance company a reason to shut you down?

Reminds me of a guy at a shop in Spokane who labeled every drawer with a label maker, even the one for spare rags. His bench was spotless but his truck looked like a tornado hit it, which always made me laugh. Most shops I have been in are somewhere in the middle, tidy enough to find a socket but not quite ready for a photo shoot.
