Happened a while ago but forgot to share. We came back from a long trip, fuel was low, the reserve was on, so dad told me to go and fill the tank. He gave me 3k. Got to the pump, told him like a boss to fill up the tank. My bad i wasn't looking at the meter, when he finished he came to me with a receipt with 3250 total. I was like wtf, what do i do now. Now i didn't have any additional money with me. I told him i only brought 3k as i thought it would be enough, he gave me both funny and angry looks. I said i can bring more money from atm (i don't have a bank account) he said, park your car here and then leave. Thankfully the petrol pump is somewhat near my home, walked home and told dad the situation, he laughed out loud saying, "chawal ma na bola tha 3 hazar ka dalwa ye kab kaha k full karwa". Ghar sa bhe kutton wale ho gaye, took the money and returned 15 minutes later, the man kept smiling at me. I gave excuses like, "ma samjha 3 ma full ho jaye ge", again he smiled at me. P.s: It was a busy day at the pump so imagine my condition.
