Maybe cause you all were just standing around talking and not fishing he figured you all did not know where the fish were, and that's all he was looking for, where the fish were! lol - j/k - prolly was camera shy is my thought. I had same thing happen on my boat, a boater came through no wake area and a different boater yelled at him. The guy turned around, so I decide to turn my camera on him (I was in a different boat than both these guys). The guy sees me with my camera on the situation, then turns and just keeps going. camera shy.....lol
