She sees a notice for a course on computers and tourism and tells her Aunt Voula (Andrea Martin), who owns a travel agency, that she could apply what she learns in the course to Voula's business. Voula agrees, and she and Maria slyly convince Gus to agree as well. The women convince Gus that Voula is handling her travel business alone and everybody else is managing the dry-cleaning store.
