premise: A man wearing blue jeans, a striped shirt, a ball cap, and headphones sits on a bench on a public street, possibly waiting for a bus. hypothesis: The man is waiting for the car valet.
contradiction: A man who sits on a bench on a street waiting for a bus is out in public, sitting, and likely doesn't have a car whereas someone waiting for a car valet is close to an establishment and not in public, generally standing, and does have a car.
