Tell that to companies.
How many people, during the credit crunch, had their house defaulted on even in spite of never missing a single payment? The bank just decided the physical property was more valuable than the debt, and kicked them out.
I will absolutely keep my word when dealing with other people. I don't care about companies and businesses, because they are amoral and I will be amoral towards them. You're a fool if you treat companies like they're people, they don't treat you that way...
