Great service on my car but bad experience with personal use of my vehicle

Service was great my vehicle was repaired in quite a short amount of time but the major problem I had is that Tobias is not the only person driving the vehicles that he repairs several times my family members saw his wife driving my vehicle which is unacceptable as she is not the mechanic working on the vehicle if the car needs to be tested it should only be done by Tobias or other mechanics working for him. I was shocked and because of this I will never be taking my vehicle back to Tobias. Great work on my vehicle but unprofessional to have his wife doing shopping or getting the kids from school what if she got into an accident with my car or got hijacked as the owner you shouldn't have let this happen in the first place and I'm sure it's not only my vehicle that this has been happening to. I am sickened. My vehicle is not to be used for your personal use.
