If 10 guys contact me for parts and ask me to hold them, 3 will actually buy it.
So I tell them " Sure, I'll hold it until anybody approaches me with money."
And out of the 10, it's usually the 7 flakers that ask 20 questions.
Look on the bright side. That kind of asshole behavior isn't usually limited to just one aspect of their lives.
So usually they have few friends, limited job opportunities, rare and crappy sex and they don't last long in small communities where your reputation counts for alot.
And you're pretty well known. I don't think anyone who matters would think less of you. I don't and I think less of everyone. :-)
