So, this book is full of plays on words. Young children, it seems, tend not to understand figures of speech, so take things literally. In this book, Amelia Belelia wants a new bike, but her parents tell her she needs to get a job to make half the money. So, she gets a job as a waitress in training. But, when a customer in a hurry asks for cherry pie, and emphasizes his request by appending "and step on it" to the end of his request, Amelia Belelia does exactly what he asks: she brings the pie to his place, then literally steps on it, squirting cherry pie filling all over the place.
Then, she sets up a lemon aid stand in front of a busy block where there's a prominent car dealer. She makes a huge sign that says, "Lots of Lemons", and places it next to the car dealer's sign. Naturally, that causes rather a lot of trouble.
Well, you get the idea. A short, amusing book with oodles of plays on words. It's not literature, but not a bad way to do some reading.
