Today fast food restaurants are very popular. One famous name is Harry's Hamburgers. Harry's Hamburgers come from America and have been in business for thirty years. There are about 5,000 Harry's Hamburgers in different countries. The food is the same everywhere. In London, New York or Paris people eat the same hamburgers and drink the same drinks.
Hamburger Harry is a special friend of children everywhere. He goes to schools and talks to pupils. He goes into different classrooms, sits down on the carpet or at the desk and asks the pupils to relax. Then he begins his talk.
Harry teaches children about litter. “Don't throw your boxes on the floor in my restaurants，” he says. “And don't throw my bags away in the street. If you see boxes and bags in the street, pick them up and throw them into the bin (垃圾箱)．”
Hamburger Harry visits children in hospitals and tells them funny stories. His restaurants give wonderful birthday parties. Parents telephone the restaurant or go there. They choose a good day for the party, arrange the food and drink and send invitations to friends. Hamburger Harry sometimes comes to the party with a bag of presents and a big birthday cake. The boys and girls sit round the tables and eat all their favorite food. They all wear paper hats and party badges(徽章). Hamburger Harry dresses in green, red and yellow and he wears two big badges. He works hard at the party. He tells jokes, sings songs and gives everyone a present. The children get colored pencils, balloons and books to draw on. They always have a good time.
Their parents enjoy the party too because they don't prepare the tables and they don't cook the food. They don't have to clean the restaurant after the party. All they do is pay the bill.
