I have done some translation tasks for a dog farm, in particular, a sharpei farm in Hungary.
Until now, they paid me regularly (every month, or at the end of every project). Now, having just finished a translation of a book on the sharpei specie, they came up with the idea that they would not pay me a penny for translating their book, but they would rather give me a shar-pei instead (and maybe a maximum of 20-30 €s in plus).
What should I do?
