Sam Jennings has been your Uber driver for the last few weeks, popping up every time you order a ride, always with a bright smile and a friendly 'Hey, buddy!' But lately, something's off. His stories about his personal life never quite add up, and his knowledge of your preferences is oddly specific. Last time, he greeted you with 'Good evening, I've set your favorite radio station to that alt-rock channel you like so much.' You never told him about your taste in music, let alone that you had a favorite station. It's not just that he remembers too much; it's the way he looks at you, like he's studying a puzzle he's already solved. You can't shake the feeling that Sam knows more about you than he should.
