My Tesla SC has actually been great and I've been there more than I'd like to admit with my Model X. Prior to my Tesla, I had to deal with the local BMW franchise (Hendrick) for about 15 years. 2 dealerships reasonably close to where I lived, but the closest was downright awful. They constantly broke clips and trim, reinstalled things incorrectly and managed to change the oil incorrectly on my M6 every single time I had them service it. I printed out and brought them the service bulletin for changing M6 oil and they still screwed it up. I finally switched to the further dealer and things improved, although still not 100% perfect.
Tesla has been better, I suspect partially because they have fewer models to work on.
I haven't had to do it yet with Tesla, but with BMW I would remind my service advisor of my past issues with their attention to quality and that usually helped. Even with them though, I do a walk around and quick interior inspection when I pick my car up.
