Look at it a different way. The casino never had that dollar, you inserted a quarter and they gave you light show that cost them a cent to put on. You enjoyed it so much, you did it four times.
Now the casino has your dollar and it's "costs" were four cents in electricity/maintenance. A much higher profit tham 25%.
