Go with your instinct.
But I would specifically ask the service writer if he feels confident that his technician will not damage the wheel. Even ask him to look at the wheels with you and confirm there is no damage prior to them pulling the truck in.
Then, BEFORE you pay them for their services, ask to inspect the truck again. If possible, with the same service writer.
If you really want to go overboard with it, take pics with your phone while the service writer is standing there.
It's unfortunate we have these issues with trust when it comes to any service center. I'm glad that my clients trust the work we do and do not need the extra boost in confidence. I fully understand that someone new to me make these requests. It's only because they've been burned somewhere else.
Good Luck!
