How about looking for a water leak in the cabin and spending an afternoon in search of only to find that someone [we won't mention names here but we're married if thats any clue] spilled water from a cup and didn't tell anybody?
How about wringing off a bolt only to find it's left hand threads? Worst thing is I've done that more than once. Uh, not the same bolt....
Anybody need their car worked on?
Cheers,
Bill
