Last year i rode in a team for a local bike shop, they gave nothing to the team but were more than happy to have a write up in the local papers letting our efforts promote them.
Why didn't you ask after the first time it happened what they deal would include if you rode for them? If you weren't happy the first time your daft for letting it happen again.
Me I'd be happy if they paid for my entry and provided a few beers and maybe a T-shirt.
