Uh...yeah.

If you want, you could buy the plastic coated socket and ask the dealership to use that socket on your rig.

You ask the dealership to do work, but complain about the manner in which the tech does it? If you don't want a scratch on it, buy your own tools and do it yourself. If it's a garage queen, then it won't matter if it takes you an hour to rotate 4 wheels. Then you only have yourself to blame when you scratch 'em.

I wish I knew what folks did for a living, and could complain as loud about them making a mistake as some do about mechanics making a mistake.
