Thanks all. It is sort of a thing I've noticed and tried to capture with regards to cruise ship decks having pockets of crew busy on smart phones and computers for reasons I don't fully understand. There must be wi-fi at sea? For some reason, these folk are either not allowed to use it or just plain don't have the time? Mr grumpy was a hard guy to get because he was aware of everything on the dock and the Sigma 150 to 500 is not a stealthy lens He'd spotted me with the 28-300 so I had to change positions. Even this shot was just in time as he nailed me a couple of seconds later.
