Sooo I was having a bad day and I got extra gas for free at the gas station

I paid for $22 worth of gas and ended up walking away with almost $2 extra for free. I saw it wasnt stopping so I stopped it and went inside to pay the difference on my card. The cashier smiled and said it was his mistake and put it in wrong and it was all good. This guy was all smiles when I walked in to pay too before I began pumping gas.

Maybe it wasnt an accident and he thought I was cute
