Zena, the woman who refills the vending machines who has made friends with most of the cabbies, admits to Alex and Elaine that she has a crush on Louie. Elaine is bothered by this, but takes comfort in the fact that Zena is probably too shy to introduce herself. However, Zena asks Alex to introduce them and Alex tentatively agrees.
Soon, Louie and Zena become an item and the gang is disgusted at the way Louie explicitly describes their sex life. In private, Zena blows Louie's cover by asking Alex why Louie won't make a single move on her. The next time Louie starts boasting, Alex tells him to give up the charade—he knows nothing has happened.
Louie then confesses to Alex that he's used to going out with "professionals" and doesn't know what to do with a "nice girl." Louie then breaks up with Zena, but she insists on a goodbye kiss before they part. She kisses him in such a way that he realizes maybe she's not as "nice" as he thought.
Zena then pulls him into the bedroom and it appears the relationship will remain intact.
