The fairies, it seems, often helped mortals who were in need. There are many versions of the story of the man or woman who shared a ‘last bite’ with a stranger who was, in fact, a fairy. As a reward, the generous person is told where to find money anytime it is needed; the only condition attached is that they secret must be kept. The money is, indeed, found where the fairy said, but, eventually, the secret is disclosed and the money vanishes.  (Foster, Ulster, 79-80)
