Honolulu, HI
I went to get an oil change. As usual, everyone was very polite. After about a week, I noticed several oil spots in my previously clean parking space, 1 per day since my oil change (indicating that the oil change itself caused the drips). I took the car back in, and they later called saying that it wasn't their fault and that I needed x, y, and z changed because the engine was in bad shape. I refused and told them to just go back and make sure all access caps/connections were tightened. Since then, there have been no leaks, indicating that yes, the leaks were due to the caps/connections. HOWEVER, the bottom line is that they tried to pile on extra services and parts when none were needed. They'll say otherwise, but it's pretty clear, 1 spot per day between the oil change and the tightening. Be careful everyone....
