There was a busker here in Boronia (outer eastern Melbourne) who used to busk with guitar and amp. I have a feeling he thought of himself as a latter-day Carlos Santana the way he used to over-emphasise his sibilants: Trouble was, for someone who owned the quality of instrument and accoutrements - he was REALLY average and frequently out of tune with what he was playing. Didn't make a lot - and I make it a point NOT to give to a busker I can hear pretty clearly from 150 yards away.

He left after about 6 - 8 months. Another turned up even louder, made even less amd left even quicker.

I tend to agree with Alanabit - a busker who works hard does deserve what he or she receives in gratuity from listeners. However - Marion says . . . who works hard to do their jobs well . . . I'm not sure about "well" but at least the best they CAN do. As a disabled musician who cannot recall chord progressions due to head injury and occasional chording or strumming or timing obscenities due to the hands not listening to the brain on that day; I simply try my best.
I do advertise I have an ABI - but not to arouse sympathy - I do so because I also have a pile of pamphlets nearby explaining what ABI is and the fact that 10% of what I get goes to the Brain Foundation.

I work a bloody sight harder than a lot of buskers I've seen - and many of them without disabilities and a lot better than me. However - do i "deserve" what I'm paid ........ DON'T KNOW. Am I appreciative of what I receive? Abso-bloody-lutely.

And one thing that makes my entertaining SO much harder is some bastard 50 yards away who can be heard more clearly than ME by people watching/passing ME!
