That's atrocious. I bet the service writer is driving your car home at night, and is using your Volt to bar crawl all over town, expecting the car to help him score with the babes. Seriously though, when I had the battery enhancement done, they had me bring the car in, they ordered the parts, and I took the car home the same day. I only dropped the car off after the parts were in.
