I chose one network of gas stations to fill up the same gasoline at the same network of gas stations. This gas station is not particularly distinguished by the quality of service. The moderately polite staff at the checkout, the operators who do not understand you on the column itself, as expected, very high prices in the store at the gas station. When asked not to top up gasoline, this request is never taken into account by operators. Gasoline is poured either "under the neck" of the gas tank, or up to a round amount...and this is despite the fact that I keep warning you that I will pay by bank transfer using a plastic card. Thus, thanks to inattentive operators, it is very difficult for me to accurately figure out the correct fuel consumption of your car.
