Fuel Saving Tips
Since taking a picture of the pump does not not work with the newer LED displays (multiplexed - some digits might go missing on the picture) I use the voice recorder on my mobile to record odometer reading, liters filled up, and price per liter quickly while waiting for the change. It beats any paper and pen or whatever. The most of today's mobiles have a built-in voice recorder or there may an app be available for free.
