First time I saw a selfie stick, my initial reaction was, 'you've got to be f'ing kidding me.' And I knew at that moment that I'd see a lot more of these dreadful things.
I remember one time I was walking through downtown Berlin behind this elderly guy who had his selfie stick extended, walking with it all the time. I have no idea what purpose that served, since he wasn't taking any photos or filming anything. All he did was annoy me, because he was walking slowly this way, leaving no space to pass him, and I was running late.
