Years ago, I was working with a customer to upgrade some older equipment to a newer technology. He refused and basically had no good reason, it would reduce cost, increase functionality, and be easier to repair. No dice, he wasn't going to even talk about it.
Two years after I left the account I read about the same guy being accused of embezzlement of over $20M from his company. He set up a distributor in San Diego (customer was in Atlanta) and was running phony purchase orders through them. He knew upgrading the technology would expose his scam because he would have been requirted to go through a different vendor.
