Filling Up at the Pump: Check that the price at the pump matches the street sign. Make sure the SALE and GALLONS displays start at zero before you open the nozzle. Touch something metal before grabbing the nozzle to avoid a static electricity fire. Always get a receipt. Contact your weights and measures authority with questions or concerns.
