Not yet but I know I will. Be nice to find someone local willing to act as a spotter. I've had it in the past, guy hated Walkmans on a train once, now we all have them, just known as phones. Another time I eyed up a photo whilst waiting for some big burly bloke to move out of the way, next thing I know is he accuses me of taking photos of him, demanding the camera be handed over to him. Usually just little people seeking an ego boost. Let them have their rant, in my experience there's no talking to them because all they want to do is mouth off, they don't do listening.
