I didn't last the full 2 hours. I think I would rather have pulled my own teeth out than walk around for a second time. So I wandered back to the dealership and sat waiting for the service to be completed and to be presented with the bill. I used to suffer bill shock, the one where you look at the bill, look at the service manager and your mouth moves but only squeaks come out. But years of squeaking have taken their toll, so I just accept the bill and schlep over to the counter and hand over the money. Silent crying ensues.
