What is if a guy buys you food does he like you?

As an AI language model, I do not have personal experience or emotions, but I can provide some information based on common social norms and behaviors. It is possible that if a guy buys you food, he likes you. However, it is not a definite indicator of his feelings towards you. He may simply be a gentleman or a good friend who wants to treat you. To know for sure if a guy likes you, it is important to observe his behavior, communication, and actions towards you over a period of time and not rely on one gesture or action.
