The trouble is that the guys in the garage might think that the wheel scuff was already there.
If I had to take my car into the dealer for work, the first thing I would do, would be to ask someone who works there to walk round my car with me and check it for any dents, scratches or scuffed wheels.
You could say to them that you know someone who left their unblemished car at a garage for work, and on collecting the car, discovered that their wheel was scuffed (or whatever) but the garage refused to admit that one of their employees did it, therefore you arent taking any chances........
