.... Maybe the idea will get around to venue owners that they aren't paying enough if this starts happening on a grand scale.
hmm.. These days I think it may actually have the opposite effect. Some club owners might think, "Oh they're gettin all that money from the tipjar, so I don't have to pay as much"..then they start lowering what they willing to pay bands, then good bands stop playing those places, then cheesy sucky bands take the spot for even less money + tipjar.. The never ending spiral of lowering live band wages..becomes the stuff many a heated TB thread started from..

Well, that's just one angle to see it from... Hey, it's my imagination, I can do what I want with it.
Just a little good natured ribbing I guess.
