Its a funny old one with the pub gigs, the last pub gig I did a month ago, we got £220, but id have done the gig for free as it was a laugh, and I only do pub gigs that are for a special reason (such as for an event, or with a deps with a band or friends I enjoy playing with, to try out a functions set etc)
If your in pubs for the money, then I think you'll always be disappointed and negative, because they cant pay what the efforts worth if its seen as work.
Also most bands aren't worth the money, doesn't matter if your level 42, if you don't bring a crowd or the pub cant draw in people your gigs, its not worth the money to the landlord, and thats understandable.
Im very grateful that most gigs pay enough to cover expenses or a meal out or trip to the cinema for the kids the next day (if I lose a family saturday night), but I am certainly not doing this for the money, its a fun hobby, just like playing football.
That doesn't mean that we play functions for free , its just that its not fundamentally a business.
