Dysfunctional Allure, the:

Widespread and self-destructive belief that performing in a bar somehow consummates a musical product.   

The prestige may have something to do with the fact that the bar is a Business or Public Place, presumably becuase such places are more discerning.  Sadly, the truth is that many of these businesses are concerned with how many friends the band is bringing, and they may only be in business becuase they depend on bands working for zero guarantees.   

Natural antidotes are Busking, House parties, and  Self-Value.
