But they WILL get things in return.... (Score 1)

They will get things in return for it though. If they charge a small fee to maybe just cover costs, then they will not cut a loss doing what they love.

They are rewarded because they get to do what they love, and other goods/services will also be heavily reduced in price. This will allow them to get other goods/services in return (instead of cash)

Also, (damn, i had another point but i forgot it ;)

Thanks for your time
