Tangential link: all this talk of discourteous drivers made me think of the last time I had a no where near comparable loaner from the *bleeping* ford dealership that cant bother to put a *bleeping* oil cap back on after my truck's FIRST *bleeping* oil change & then *bleeping* argued with me about performing a proper cleaning of the engine compartment & took 4 *bleeping* days to do a very half a**ed job.... i put my finger in the battery tray up to the top of my fingernails in *bleeping* oil, this is after they 'cleaned it'...

Very tangent, but I always check everything that I think was touched. Including tire lugs now! Yup, I have to take a tire iron and check them.
I get strange looks but no one has ever asked what I'm doing.
