When I worked for Rank-Xerox, we refurbished a Copyflo machine (a large microfilm printer). It took several months of work and cost a lot of money. The delivery truck was backed in with the roller shutter part way down, the machine was loaded and tied down, and the truck went on its way. Unfortunately, no-one had thought to raise the shutter to clear the machine, and it ended up on the floor, completely wrecked.
