Strange but true, the Tax Office can be your friend. Look for example at the Dutch case, the local "belastingdienst" has launched a campaign to explain to young people how they can get some money back if they fill in and present the right form.
The initiative consists of nicely illustrated website that offers a bunch of tips and a series of amusing TV spots. My Dutch is good enough to enjoy the creativity, but I don't dare explaining it publicly. Anyway if you watch the videos n. 3 and 4 you can understand them and enjoy them even if you don't speak Dutch.
