Same story at my office, and the guys could care less. As others have stated, to some of them, it is a kind of revenge for you having a nice, clean car and they have a 15+ year old rusted pickup, I can almost hear them saying, "We'll teach him to have nice things...."

I do not have the luxury of being able to walk to work or park far enough away where they can not get me, so I have to take it. There is a layer of dust on my car so thick after 1 day of not washing, that I am afraid to even use the california duster for fear of scrathing the paint

I feel your pain.
