A convenient location at a transport interchange, near a car wash, a coffee shop, you can slowly refuel and wash the car, drink coffee with pastries. Entry and exit to the roundabout, without delay.
Where do you recruit such operators, it is rare that at the gas station you have a softer operator (hospitality 0), as if everyone is refueling for free. I fill up a full tank, wait, ask, finished in response, well, of course you can't call it a face, such a facial expression, as if I owe her a million.
I refueled at this gas station on March 10. The service is 2 with a minus. The cashier is rude, besides she served with a favor. The waiting time took the gas station and the rudeness of the cashier more than 15 minutes.
