I enjoy the colour they bring to a day out so I do reward them. It is their livelihood so I guess they wouldn't do it for free no matter how much they enjoyed it (who works for free these days).
The ones that put me off are ones who sing off key, makes me wonder what they are doing there.
I believe they All have a place.
Even....if they really are not as good as others.Some may have mental health issues, so it is a way to make a little bit of food money.
I say''bless their hearts for trying''....If I have money on me, I always give.
I enjoy watching buskers very much and will drop coins in after. My favourites are Funky Bunny, Uptown Brown and Metaphysical Groove that I've seen within Melbourne. I think they have facebook pages if you want to check them out. Very talented and friendly people.
