The major difference is that a ticket is a perishable item. She entered a binding agreement that, in exchange for her money, she can have the tickets. Had she not bid, and won the tickets, he could have sold them to one of the other apparent bidders and he, himself, would not be out any money. She was wrong. This was a mistake on her part, not his. However, with that being said, had this guy not been a douche he would have sold the tickets to her at face value (maybe + gas) but nothing more. In the end, they are both in the wrong.
