At a dealership I used to work at, our parts truck was always a brand new Ranger. The Parts manager who drove it home every night had OCD. When I or the owner of the shops son would take the truck, we would use the washer fluid until it was gone, even on sunny days, upon our return back to the shop it would be empty. I worked in service at the time, when the parts manager would find no washer fluid, he would ask me to have a tech look at it, as it always seems to leaks out and being pretty much brand new it should all be there. He would also have the blower, temp and vent position knobs pointed up, we would move those around and blare the radio, so when he started it, radio would be a full bore and blower be going also.
