Where to refuel at Prague Airport ?

There is only a gas station in the direction of leaving the airport near Prague airport. After refueling, if you follow the normal driving route, you can only run on the highway out of the airport and cannot return to the airport. I have been taken in. After refueling, you should exit the gas station from the entrance where you entered the gas station, and then take the left lane, so you can get to the roundabout ahead and go back to the airport. The previous time when we returned the car from CK to the airport, there was no service area or gas station on the 50-kilometer highway near the airport. It wasn't until the airport that there was one, and it was still in the opposite direction. We encountered the strange thing mentioned above. I suggest getting off the highway near the airport, refueling, and then getting back on the highway.
