I've met a fair few grumpy anglers while boating, but far more frindly ones. One once "caught" Phoebe while I was cruising past, I asked him if he wanted me to stop but he said no spent a couple of minuites following me down the towpath before he managed to pull the hook off (it was caugh near the bow somewhrere below the waterline, possibly an anode?), we had some good banter, he obviously accepted it as one of those things that happen. Anther time I felt really guilty when I opened my engine room doors after running my engine for half an hour to find an angler sitting between my boat and the next a couple of feet from my exhaust, I was very apologetic, because if I'd known he was there I would have at least warned him that I was about to start the engine, he said something along the lines of "You gota do what you gotta do, can't be waiting all day for me", which I found very reasonable. All in all I've probably met more unsociable boaters than I have unsociable anglers, I see boats moored on lock landings far more than I see anglers on them, I think both groups are a largely good natured and helpful lot but both, like all groups in society, containing their obligatory grumpy/unsociable/psychopathic elements.
