premise: A man is making a purchase on the street while other people wait. hypothesis: The man is buying food.
neutral: Just because the man is making a purchase on the street does not mean that he is buying food. He could be buying anything on the street, such as a newspaper or magazine, while other people are waiting. Also, just because the other people are waiting does not mean that they are waiting for him - they might be waiting for a bus, while he makes his purchase, and the two events don't necessarily coincide at all.
