It is very inconvenient to refuel. First insert the gun, go to the operator to tell how much fuel, then return to the column, press some lever, fill up the fuel, go to the operator again to pay. There was no movement because of a simple action. Maybe it's possible to simplify refueling a full tank????
There are so many denials for this company and refueling, in the morning it will not work urgently (with 2 columns working, they come up with a check-in from one side). And will everyone stand on the same column???
