Just Rambling Along (S)

A man and a boy both notice a wallet that has been left on the sidewalk, but the man relinquishes his claim to it when the boy's father, a policeman, arrives. Soon afterward, the man joins several others in following an attractive woman into a cafeteria. When he is ejected because of not having any money, he goes back and tricks the boy out of some change, and then makes another attempt.
