As for JiffyLube, IMO, ain't damn thing going to change.
For the folks who don't service their own vehicles, you can always ask back for the old part. But now it becomes is that a part from your car or someone else's. I usually try and go someplace where I can watch them.
If you have a place where you can work on your car, it's worth it to do it yourself. I rather screw something up myself than let some clown like JiffyLube screw up and try and cover it up. Someone here mentioned that they forgot to put oil in an engine before it blew up.
