Whenever I have tire service performed, I also remove the center caps on all 4 wheels and leave them at home. No chance for them to look elsewhere in the car and attempt to re-install. Keeps the Service Shop from scarring up the wheel while prying the center cap off. I usually remove the center cap with a plastic pry stick (like from a set of interior panel tools) or use my driver's license to slide along the edge until I can pull the center cap off.

I also have a set of McGard wheel locks on my 2007 Coupe. I remove them & re-install the standard lug bolts so the Service Shop doesn't have to deal with them. When I get back home, I remove a lug bolt on each wheel and replace it with the locking bolt. And I always tell the Service Shop to torque the lug bolts to 80-85 ft-lbs. The spec is 81 ft-lbs on the Crossfire. Most shops will torque to 100-ft-lbs w/o looking at proper value for car.
