That Aikatsu Person
I'm certainly no legal expert, but I think it depends on the cinema and their policies. Not sure about refunds but I know from friends' experiences they've at least got a ticket for another screening when there's been technical problems.It has been disappointing that there's been so few subtitled screenings (and that there hasn't been one near me, but that's the nature of the game).
Though, as the definition of "goods" in the act is "anything physical which you can move" I'll be surprised it it actually applies in this context? Especially since there isn't a transfer of rights or ownership.
