Playa Larga taxis

Hola.
A good taxi story. A few months ago we were going home from centro. It was after midnight. We usually pay 50 pesos after midnight. Our driver said he had no change. We gave him 100 pesos and wrote it off as a loss. A week later, we were going home again after midnight and this taxi driver insisted that we come with him. Got in and realized it was the same driver with no change a week earlier. No charge. We gave him a tip anyway.
