This is why you can't trust anyone to work on your car.

IMO, Stuff happens. No ones infallible. I remember when it took me a quart and a half of oil before I realized I forgot the drain plug.:oops:.... #-oThat was a mess!
I'm sure many here have had do-overs in there dealings with cars.

A six point box end combination wrench and dead blow hammer if needed works for me on removal of the oil pan plug.

Had an instance last year the local Chrysler dealer leaving an oil filter loose on our Sebring. They were more than happy to make it right and no waiting to get in...........
