Last time I was at a lube-x place they had trouble threading the drain plug back in. I said well just chase the threads and try it again. The managers reply was that they could not do that because it would be "above" the drain guys skill and pay level. I would have thought damaged pan threads would be an everday occurance in that line of work.

The guys they hire are just high school students with little or no training. Anyway we managed to thread the plug in and seal.
The thread damage was not their fault, that honor goes to the idiots at the local Fountain tire who have also overfilled it and forgot to tighten the drain plug altogether on another car.
Now I only take the cars to the local Honda dealer. I always check for the oil pressure light at start up and check the oil level when I get home. Never assume anything...
