I had an appointment at 9:30 for an oil change. I arrived at 9:20., checked in and was told to wait in waiting room, it would take about 45 minutes to an hour.
At 10:00 am I was told that they needed to use a special lift for my car but that lift was being used and wouldn t be available for another 25 minutes. I ended up being there for 2 hours for an oil change. Why bother making an appointment?!
