One of the things I like best about a sex story is the feeling that I know the people before they start copulating. That's also one of the main characteristics of Delta's stories.
In this case we have a man who is a genuinely nice guy who drives a taxi. A "lost fare" can refer either to a person who bums a ride for free by not having the money to pay the fare or to a person who stops riding a cab because she wants to stop being around the cab driver. In this case we have one of each, but then none of either.
First our hero counsels a teenage hooker to go home to her parents. Not only does he not collect a fare; he also pays for her train ride and gives her some money. Sucker! Then he has sex with his favorite customer at a time when she is distressed, fully aware that she'll wake up the next day and have to avoid even making eye contact with him anymore. Too bad!
Not!!
