Here's the most stupid question in all of the thread.
How do I correctly refuel car?
I just got my license and I need some help.

At gas station there are all the pumps and picture related display where you select language and where to pay (with card or at inside store). Walked by the gas station and took pictures.
Do I first
>A) Select how I want to pay, take the pump, put it into car, refuel & pay
Or
>B) Take the pump, put it into the car, refuel, and then select how to pay.
