回答楼主关于油费的问题。Budget这么大的公司，不会店大欺人的。

Why do you charge so much to refuel the car? Answer: Unless a customer has chosen the Fuel Service Option, which is competitive with local gas prices, we prefer that renters stop at a local station and refuel the car before returning it. If the customer chooses not to do so, we charge a premium for providing this refueling service to them. That charge takes into account both direct and indirect costs of having to refuel and maintain our refueling infrastructure for customers who prefer this service. The charge also is intended to strongly motivate customers to save by refueling the car themselves.
