The excerpt also reminded me of an H. Ross Perot story that I cannot seem to find anywhere online. Someone had approached him for VC and had a sound business plan. The person had had issues with alcohol in the past, and had sworn off it. Perot had learned this (probably from a PI), and at the moment they were going to sign a business deal, Perot insisted on closing the deal with a drink. The other party explained that he did not drink, but Perot was absolutely insistent and would not close the deal without a drink. So the guy left without a deal. The next day, Perot called him and closed the deal. Perot had been testing the resolve and reliability of the guy. The venture was a success and became a Fortune 100 company.
