Input: Text: i work as a gas attendant at a gas station in a shitty little redneck town. last night i had a father and son pull into my pumps to obviously fuel up. when they pulled up, they were clearly not in front of the diesel pump. instead they parked in front of the regular unleaded gasoline pump. while the men were standing there i began to pump their gas. i had not payed enough attention to the truck to notice that it was in fact a diesel truck. i put about $30 worth of regular into their tank, handed them the receipt and wished them a good night.  this morning i got a phone call from my boss informing me of the mistake i made. now my job is on the line because our company is having to pay to tow the truck, while i will most likely be paying for the repairs. now i must pass a drug test and hope that i get to keep my shitty job. although i believe this wasn't 100% my fault, i still fucked up big time.
