I always refueled here normally, and the last time they refueled propane with water, after that the check lit up, the engine started shaking, especially before a long trip, switched to gasoline and drove off. They've gone bad, and I don't recommend setting foot here anymore.
The price of gas is acceptably much cheaper than at other gas stations at once you can fill up 3 - 4 cars, not such a big queue, but the minus is that after refueling, you drive a little along the mileage, they don't top up the mileage a little, another minus comes out from the gas station to go back to the city, the U-turn is very far away
