If I was an auto parts dealer and someone came in with the alternator they
had removed from their car themselves, I might tend to assume that person
knew enough about what they were doing to not need my input (and in fact
might be hostile to it for that matter--how many times has he gotten the
evil eye from someone with the attitude "don't you see the grease on my
hands, buddy? I know what's inside an alternator!"). Nothing in the
original post says that he was being advised by the people at the store to
replace rather than repair.
I agree that greed is rampant and that you're as likely to find it at an
auto parts/repair place as any other, but I don't think it's fair to slap
this particular Advance Auto with that label until we have more facts. I am
not disagreeing with what you said about the temptation to keep making money
off of people who would be better off if you helped them help themselves. I
just feel that it's hard enough to run a business and do it well, and before
we cast doubt on someone's reliability we need all the facts.
