So, it costs $30 to get from his city to her city. Presumably it also costs $30 to get from her city to his. So, theoretically, she could return to her city as originally planned. Then cousin could pay $30 to get her to his city, plus the $30 he already plans on spending to get her home. Instead of $30 from cousin, RedneckGravy is supposed to spend $40. Then to add insult to injury, she doesn't even get any benefit from it. Sounds like a perfect time for, "Why would I want to do that?"
