Sarah's surprise

It is Sarah's first day in the  cafe. A man comes into the cafe, takes some food, but does not give any money to Sarah. What does she do?

This is a story of an event in a cafe. The man takes some food and does not pay money. When I read this, I thought  he was a thief but surptisingly he was the husband of aone of the clerks working in the cafe. I do not think this story so interesting but I like the illustrations of this book.
