I don't really believe the price of petrol will kill the music scene. It'll just raise the price ... I still drive long distances. It just costs me more, so I expect to earn more ...

I do see it as my responsibility, or at least my shared responsibility to get a crowd out to any club I am playing. So I am OK with setting fees based on he door. In the US most clubs have a guaranteed fee as a base, with a percentage over the minimum. That works for me. If the club earned at least that break even number, then the show is in the black and I feel like I've earned my keep - that means I'll likely be asked back too.
