Flash forward to a year ago when I bring the car in to the dealership for something specific.
Mech: We did our standard gagillion point check and you have a serious problem with your fuel pump!
Me: Just fix what i brought it in for.
Mech: If we don't fix your fuel pump you could be stranded on the side of the road!
Me: Just what I brought it in for.
Mech: If we don't fix the pump your car is going to just die on you!
Me: No. That's just how Fords are. When they get older it takes a long time to crank and turnover.
Mech: That's idiotic, who told you that!
Me: Your mechanics told me that when I brought it in nine years ago while it was under warranty. If you really think they were wrong you can fix it for free, otherwise just fix what I told you to and stop bothering me.
Mech: Uhm, OK. We'll fix what you brought it in for.
