It would be horrible to run out of gas on the road , so its good to have it filled . I check the prices and proceed to the store counter . I make sure I park my car by a gas pump and look above at the number by the pump . The sales clerk asks how they can help me and I ask for twenty dollars at pump number 5 and if in can have regular gas . The cashier gives me a receipt and then I head out the door , back to my car and open the gas tank . I put the pump in the tank and hold the handle so the twenty dollars of gas I just purchased gets fed into my car . Question: When did they drive to the gas station? Option1: After running out of gas Option2: when they needed gas
Output (English): when they needed gas
