What do you mean you don't refuel the bus?

Not refueling the bus means that it is a joke that the bus runs too fast. Don't refuel if you describe too much. The bus is convenient for ordinary people to travel, and passengers from all walks of life cannot do without it. Sometimes passengers miss because they are afraid of missing the bus. Check one step. They will helplessly say that it runs really fast, so don't cheer for it in the future. Actually, it's just a joke.
