Long Wait time.
I went in for an oil change and tire rotation and balance, and while everything was done properly (to my knowledge) an hour and 45 min is just too long for what was supposed to be an hour. My car was in the garage area for a total of about 20 min yet I was there almost 2 hours. Had I know it would be that long I would've rescheduled. The guys were nice though and semi apologetic.
