While it's probably worse at dealerships, this pretty much applies to most service centers. They don't put the certified techs in the oil change area.
That's where the "cheap" labor goes, and you are getting what you pay for.

I once took my wife's car in for her free change... one of the "techs" was changing the tranny fluid on the car beside hers and dumped it all over the passenger side of our car accidentally. Apparently he sprayed a little water at it, and then walked away.

I didn't find it until I got home. The manager got an earful, but it didn't change what happened. If I hadn't noticed it you can imagine what that paint would have looked like a few days later.
