We cleaned a sofa several years ago and the customer called back to complain that the area under our tarp was darker than the surrounding carpet. When I looked at it I figured out that it was just the light from outside casting a shadow on the carpet. Even after I left she wouldn't let it go, so I went back with a 4 ft x 4 ft piece of white carpet and laid it so that the shadow line split it in half. I then moved the carpet around and of course the line also moved all over the carpet piece. She was convinced I was doing some sort of magic trick or something. I had to finally tell her to get her own blanket or sheet and try the same thing...
