Let me translate what's on the paper that he holds :
"Value your art with your coin.
Thank you for your attention."
I still remember, not so long ago, guys doing those human statues just for fun. Well, a coin here, a coin there, who's to complain ? But now, if someone takes a photo and don't throw them a coin, they just look at him and point at the coin bowl. It happened to me, but i did it on purpose, just to see if that was true.
And it is !Ok, it's their job, and they deserve to be paid for it !
I just don't agree with that "imposition".
I've heard, don't know if it's true or not, that a guy took a picture at one of them, didn't throw a coin, and his camera was smashed to the ground by by their "manager".
If it's true, is quite sad !
