it is always great to hear about standup companies these days, as everyone knows how chaotic the world has become.
i had a similar experience yesterday, although not pertaining to auto parts.
a few weeks back, i stopped at an ACE hardware store in a neighboring town to purchase an extension type of spring to replace one that broke on a "hand squeezing" thing you use to strengthen your hand muscles/grip.
the replacement spring worked well, then the one end broke off. i didn't think my grip strength improved that much.
anyway, i was in the area and stopped for another spring. as there was two in the bin, i got both.
i told the cashier lady i needed these springs because my "hand squeezing" thing was turning me into Popeye, and i was growing big and strong !
without batting an eye, she said no problem, "i'll only charge you for one spring".
i told her i tossed the sales slip, and it's no big deal, because these springs were only $2.49 anyway.
she insisted on charging me for only one, however !
well, ok.
i went to this ACE store only because i knew they had a larger hardware selection than the ACE store down the block from my house [and they have a large selection !], and i had a doctors/hospital appointment in that town anyway.
it's small things like this and others mentioned, that gives a guy a good feeling about his fellow man.
