| The younger members of most American families don't like foreign food. They like hamburgers. T  heir idea of a good meal is a hamburger, served with ketchup and French fried potatoes, which are called French fries. French fries are not considered foreign; most American children and teenagers love to eat them any time of the day or night. Millions of hamburgers and French fries are eaten every year. Thousands of roadside restaurants prepare and sell them. These are not really restaurants in the usual sense; they often have little space for tables and chairs. Many people buy their hamburgers and take them home to eat, or eat them in their cars. Sometimes it is not necessary to go inside in order to buy the hamburgers. They are ordered through a window in the restaurant and then are handed out through the window to the waiting customer. Sometimes the customer does not even have to get out of his car. When an American family travels abroad, this is almost always the custom that the younger members of the family miss most. | ||
