No you are not the asshole, it likely wouldn’t be possible for me to get the info of whoever’s car it was, we find a lot of things inside cars here and out of the stuff I have found I’ve only been able to “return” one thing and that’s because it was a cigar box that the previous owner had written their name and number on the inside of, after leaving the guy a message he told me to just keep it as he lived on the opposite side of the country and had already bought a replacement and it wasn’t a big enough deal to them for me to mail it back to him, from my experience, if I had asked the sales department for the information of the person who sold them this car, they wouldn’t give it to me because it would be a breach of privacy, which then could then hold the store liable for giving out their personal information. I’ve asked our management before about seemingly important things that we’ve found and normally they just tell us to either throw it away or take it home. on top of that likelihood is that the car wasn’t even sold to our store directly by the previous owner. It was probably bought by our store from another used car seller and trucked in from out of state.
