I did not know how to fill my car with gas when I first arrived in the United States. In the Philippines, you just pull up next to a gas filling station. You don’t even need to get out of your car, an employee will go to you. Just roll down your window, tell them how much gas you want and they’ll do it for you.
In the United States, that is not the case. Filling your car with gas is a do-it-yourself process.
