I had an appointment for a routine oil and filter change at 8:40AM. At about 11:00AM, my service advisor informed me that my truck was on the rack. About 30 minutes later, it was done. Virginia gave me a discount for the inconvenience. Fast forward to 5:00 this afternoon, and I see a puddle of oil under my truck when I went outside. The "mechanic" failed to tighten the drain plug in my oil pan. I tightened it myself and checked the oil level, but I seriously doubt I will return after this experience.
