Do yourself a favor and keep tabs of the amount of times they actually vacuum your car when you do an oil change. Unless you are a good looking girl with your tits hanging out, it won't happen. It happened to me 4 times IN A ROW, even after I asked the guy at the counter, "Do you promise they will vacuum my car like the sign says?" - Yes Sir, we vacuum all cars!"
I got in my car and Voila! No vacuuming of the front carpet. Of course not in the back. "F" Jiffy Lube.
