Too Dear for the King
Many years ago an English King who knew very little about his people left London to travel in the country. He wanted to see how people in villages lived and what they did. During his trip he made stops in different places to spend the night or to get some food.
One day he came to a little village and stopped there to have breakfast. He asked for some coffee, bread and butter and some eggs.
A farmer prepared his breakfast and the King ate bread and butter and two eggs and drank a cup of coffee. Then he asked, “How much should I pay for my breakfast?” The price was very high and the King didn’t like it.
“What?!” said the King. “So much for a little bread and butter, a cup of coffee and two eggs? Isn’t that too dear? There must be very few eggs in your village.”
“Oh, no,” answered the man, “there are many eggs in our village, but these days there are few kings here.”
