A brilliant picture book about the importance of gratitude, manners and kindness, all wrapped up in a madcap hotel adventure that kids will want to read again and again. Meet Hanz and Franz. They're waiters in elevators. In the Rigatoni Hotel … Hanz and Franz are the world's most diligent waiters and they think of the Rigatoni Hotel's loyal guests as friends, and their fellow workers as family. But when no one says please, much less thank you, it starts to wear on our waiters in elevators. Will they hand in their resignation at last? And how will the hotel and its guests cope without them? Â
