If I was Chant's amusements, I'd counter sue them tbh. It's honestly stupid if they think that they could actually win this given that she was stupid enough to walk into a restricted zone. Pulling the whole "The staff should have done more to stop me" card is just pathetic.
Staff member said they can't retrieve it until later when it's safe... the area is fenced off. As far as any sane person can see, that should be enough to go "Hmm... maybe I shouldn't do this" but apparently not. Absolutely zero sympathy for her or the family tbh. She made a stupid decision (taking the loose items on board), followed by a second stupid decision (going into the ride envelope) and now she's making a third stupid decision by trying to sue someone for their own stupidity.
