Have you ever been driving at night when you’re very tired, but close to home, and the gas warning light goes on? Do you go home and take care of it in the morning? If you don’t stop to refuel now, will you worry that you won’t have enough gas or energy to get back to the station tomorrow? Whatever causes the least stress is your best bet. I’d rather fill up than worry about it in the morning, but others would take their chances. Whatever works best for you should be your plan of action.
