They shouldn't be messin' with the devil.
(That's an inside joke, you'd have to have read a certain other thread to get it.)
Seriously, what jackasses. That's what I hate about all these service places like Jiffy-lube and such, I haven't used them in years but you can always tell they're following a script. They must think people are complete idiots.
Edited to add: Back when I had a '93 Saturn, I brought it in and planned to wait. They said it would be longer than expected, so I called my staff assistant to let her know I'd be later than I thought. The service advisor comes up and is talking with the receptionist where I'm using the phone. The SA must have figured I wasn't listening since I was on the phone, and tells the receptionist, "I hate it since they put us on commission."
When I got off the phone, the SA tried to push a cartload of crap services I knew I didn't need. Told her to just do what I came for, thanks.
