Hi, I had case a couple of years ago at a main dealer I worked at. Customer comes in with a brake noise. Tech looks through the wheels and says it need pads soon. told workshop foreman, who told front desk, as they were busy booked her in for 3 weeks later. Customer still had noise and went kwik fit. Brakes replaced. Cut to a short story, trading standards were taking us to court because we had allowed a car to be taken by the customer which required fixing. After that we got customers to sign that they were taking a car away that had any reported fault!
