I know a man who isn't a billionaire but probably in the 50-100 million range. He sat down with me at a recent party we were at and talked about saving money on fuel with dockets via apps he uses when shopping. I was polite and interested. It was not a thing I expected to hear. My take away was to just keep driving my small car, and not require such hustle to fill up a Range Rover. :D
