There's a Toyota dealership near me that I will never visit again. Call them LBD.
Many (many, many) years ago, I owned a 1986 Toyota Supra. I took it into LBD for service. Pretty major service including a full lube and a check of the timing chain. Got the car home. A couple of days later I had some reason or another to look under the hood. To find several screws sitting on top of the engine and the timing chain cover loose. So I took it back, told the service manager that this wasn't acceptable and had them fix it. No problem.
About 3 weeks later, I was driving back from Burbank airport with my then BIL. He'd been on a road trip with friends and got involved in a pretty serious auto accident. He was fine, but it had been rough on him, so he was a bit sensitive to car problems. Suddenly, my car starts grinding in the back and slowing down. I manage to pull into a service station and find a phone (pre-cell phone.) Got it towed to a Toyota dealership in Burbank that I had dealt with in the past and liked. They looked at it and told me that the differential was completely dry. LBD had failed to torque down the drain plug when they changed the fluid. We were lucky it hadn't seized entirely at freeway speeds.
LBD insisted on fixing the problem, although I wanted the Burbank one to do it. Fortunately, they did get the repair right and I drove that car for many, many years.
Some years later, my then-wife was in the market for a Camry. She went to LBD and had some of the usual go-around with the salesman. She told him, clearly, that she was buying this for herself and it was entirely her decision -- she didn't need to have her husband there. When she was ready to make a deal, though, she did want to call me and tell me about it. Not to get permission, but just to inform me. The salesman had a fit about this. "You told me you didn't need his permission... " yadda yadda. She walked out of there at that moment. Bought her car at another dealership where she got great service.
