Fuel Ends in During Journey?

I and my cousin rode on a motorbike to go to our other cousin's place. She was also riding her own motorbike. We went through a short cut meaning not the highway but the roads are paved. Then suddenly the mootbike just conked out and no matter how my cousin started the engine it never started. We were in a middle of a very unpopulated place. Now my other cousin had speeded away not knowing that we were not moving. Unfortunately there were no other passing vehicles and I walked up to a house ahead and ask if there's a mini store that sells gasoline. The guy was not very welcoming so we just texted our cousin to bring gasoline if ever she can pass by a store. No gasoline stations at this place. Well after some 30 minutes or so she came back and had one liter of gasoline suctioned from her father in law's motorbike. LOL Lesson learned? Never to rely on the gas gauge because it said half full but it was empty really. The next day we had it checked.
