I had my car oil changed and I gave the manager my discount coupon packet which they sell for $20. He credited the oil change but did not return the rest of the coupon packet. After the oil change I opened the hood and it was the messiest oil change I ever had. I got oil drips and spills all over the engine. It looked like my engine took an oil bath, unbelievable!
That's the first and last time I'm going to get a service done at Tire Works.
