Saw this street musician playing the cello at via Carlo Alberto, a kid came forward and offered him his appreciation.
I took the photo, but then the musician looked at me and shook his hand to signal his disapproval of being photographed. Well, too late, already done.
I do respect street artists a lot, but as far as I am agree with privacy, exhibition in public doesn't really scream privacy to me, let alone performance which request an appreciation in the form of money.
While the kid shown his generosity, the artist failed to do so.
I normally offer some money after taken a photo, but in this case, I just moved on....
