Some people must just look for an excuse to moan, which is clearly the case here.
This is not about moaning but money. Most likely she didn't even come up with this on her own. Some lawyer she knows saw an opportunity here.
Technically speaking she could even be right in this case, who knows. All I'm trying to say is that with all the insurance companies etc, people always lose even when it's a clear case. This time they won and generally speaking it's good news of course.
She's not a fan and she doesn't care about the band, therefore, she wanted her money back. Simple really.
