I've seen them do this as well. For some reason, they didn't for me this time.I have seen Techs at the service centers taking videos of the cars when they are dropped off. I do the same for the interior and exterior of my car. I let the service advisor see me do it. This is an example as to why.
Even the staff was like "for some reason I don't have photos of the before"... when I got there, they had the body shop guy come look over my trunk issue, and he just took it from the entrance office with no mat covers or steering wheel covers and no photos/video. Just hopped in and took it right after I showed the trunk issue.
I guess I will have to document from now on, but I'm going to fight this damage until they cover me. There is no way I'm accepting that they can just damage my steering wheel and say "oh well, sorry".
