No...she knows better than to go to that area, and always pays with a bank card at the pump.
On a serious note...the stress she was under at the time had a lot to do with it...not her normal demeanor, and had it not been the complete run around we got during the whole experience certainly would have resulted in a different outcome, for sure. Again, I don't excuse her actions, but will defend her right to do so in the heat of the moment.
So if you were standing in line with her at the grocery store and the person behind her starting calling her colorfull words you would tell her "Its ok honey, its his right to do so"?
