When Okabe regains consciousness, he finds that the lab members are preparing for a party and that the Future Gadget Laboratory's electricity bill has skyrocketed due to all the experiments. To compensate, Okabe tries to wait tables and decides to sell the latest Future Gadget. (Partially taken from the Steins;Gate wiki).
