I had to go to a customer site several years ago and pick up one of our shipping computers after their warehouse burnt to the ground. My company wouldn't just take their word for it, or the police report, or insurance, or fire department for that matter. Went to the site and nothing was left of the building. Had to dig through the remains and pulled out a 60lbs lump of plastic and metal. Had to ship it clear back to our corporate office so they could verify it was indeed a goner.
