At least in London some people might turn up, and maybe one of them will be in the music industry.
I had a soundman refuse to take a DI post EQ 'cos he said my EQ was too extreme, before he'd heard it, or tried it. I said "I like my EQ like that, aren't you just supposed to make me sound louder?" and he said "no, I'm supposed to make you sound good", which has to be the most arrogant thing i've ever had said to me. Still, I just let him do what he wanted. Everyone thought I sounded crap in the audience, but it sounded good on stage, so I enjoyed myself. It's good to have a relaxed attitude towards these things.
