As a employee of a gas station you help the customers filling up the tanks of their vehicles. Stay friendly and don’t let the customers wait too long, because then they’ll leave the gas station unsatisfied. Take the money from the customers after filling up the tank and put it in the cash register. The more money you earn, the higer your score will be. And the further you’ll get in the game, the busier it gets at the gas station. Can you keep all customers satisfied?
