I know this isn't a serious, constructive contribution to the debate, but I just came across it an hour or so in James Patterson's
"You've Been Warned":

"I turn to the stringy-haired guy plucking away on his guitar, every
other chord off-key. His ragged guitar case lies open at his feet,
and I glance at the torn black velvet lining sprinkled with spare
change. And I do mean spare. A quarter or two is the mother lode for
this troubadour.
   "I'm serious, lady," he barks. "Beat it! Get out of here!"
   Before I know it, I'm right up in his face too. "Listen, you
sorry-assed Kurt Corbain wannabe, did you ever think that maybe it's
your playing that's hurting business and not me?"
