I was going for a long drive, so I knew my car would need more fuel than it already had. I pulled into the station and checked the dash to be sure I knew what side the tank was on before I parked next to one of the pumps. I pulled the lever inside to open the panel for the gas cap and hopped out of my car. I paid for my fuel at the pump using a credit card, and unscrewed the gas cap. I slid the nozzle into the fuel tank and started to pump. I watched the gauge carefully to be sure I knew how much I was getting, and how much money I was spending. When I had a full tank, the pump stopped all on its own! I put the nozzle back in the holster on the side of the, screwed the gas cap back in place, and closed the panel. I was ready for my trip! 
Question: Did they have to wait long to use a pump?
no they used the pump right away
