When I was called to tell me that my car was done, I was told that the battery was dead because the doors were open during the windshield replacement and iSight calibration. Since I am sure that this is not the first time this has happened, it would seem to me to get a battery conditioner (used for storing batteries in the winter) that only puts out maybe 2 amps and attached it to the battery during the windshield replacement and iSight calibration so you do not flatten the battery during the repair. The worse thing you can do to a car battery is to drain it as it shortens the life of the battery. While the battery is not in new condition, this will only require me to replace it sooner because of them draining it flat.
When I opened the car door to get in, there were muddy foot prints on both front door sills that I had to ask them to clean (both were spotless before I came in). And easy fix would be to get to rug with rubber backing to place on the sills of every car so you don't scratch the sills and I would go one step further and put a rug on the garage floor to wipe your feet before stepping on this run on the door sills. A quick vacuum would be a nice gesture too. Make the car cleaner than when it was brought in. Customers will appreciate it.
Then the passenger side wiper was reattached too high and was in your field of view and catching air because it was above the hood of the car so that had to be moved down to where it was before I took it in.
Then as I was driving home, I notice several places were finger smudges on the headliner and visors from the installers hands.
