The fact that a band is playing your venue does not entitle them to come and conduct commerce on your property
What if they decided to try and sell groceries, or rabbits, or whatever they’d like because “people wouldn’t be here if we weren’t playing”
People wouldn’t be there if we didn’t build the venue either
We’re all in this together…all of the income streams like merch and bar and ticket fees go towards paying the band
I have always found that people accusing others of trying to make money are only upset because they want that money themselves
