Jack took the card with one hand, then gave the agent his system card. Agen took the card in his hand, and from his backpack he grabbed the card swiper to swipe Jack's card, but Jack gestured for him to stop.
"Sir?" the agent asked in a confused tone.
"Withdraw only 300K€," Jack said then. He put his hand into his pocket, grabbing the cashback card in his hand, which he had previously purchased for 200K€.
As the agent swiped the card, Jack mentally said, "Use," and then the cashback card disappeared from his hand. He immediately checked his balance on his phone.
[Balance: 1,047,000 €]
A solid 349% Crit.
Jack, seeing the balance, sighed with relief, then smiled cheekily and said, "Now withdraw the rest of the 250K€."
