It's probably not logical but its how she feels. She's almost certainly just miffed that she didn't get one! As anyone would be really. Also she's predicted grades over the course entry requirements, so she feels by not getting a uif, they just don't really want her that much. Not only did they not give her a uif, they gave her two completely incorrect offers before finally giving her a standard offer.
She'd feel compltely differently if there were 5% uifs, but 40% is too much imo.
