You might have to check with British law, but here without your consent they can\'t charge your credit card, make it clear that you don\'t want to pay for the game (that is, you gave consent when you gave them the card against future late/penalty charges, but you can tell them not to charge the card, if they do, VISA will reverse it at great annoyance/cost to blockbuster). They can only ask you to pay what the demo is worth, so they might argue that to replace it would cost the cost of veronica X, but since DMC is now out, and I\'m sure they\'re renting copies, I don\'t think that they would win such a fight. Talk to the manager, as for some reasonability, offer 5 bucks, and give/show him the broken disk so he knows you aren\'t stealing it.
