Cold drinks for the fisherman who pumped my tire near Ojo de Agua

My bicycle tire went flat near Ojo de Agua at midday and I walked it for a kilometer in the heat. A fisherman mending a net on the sand got up without being asked and brought a hand pump from his truck. He pumped the tire himself, checked it with his thumb and went back to the net. I thanked him four times. He nodded once each time. I have cycled past every Sunday since with two cold drinks in my basket. He is usually mending. I think it is the same net.
