Mr. and Mrs. Jones had no car of their own when they first came to the U. S. Therefore they went to work by bus every day. On one weekend, they wanted to go downtown by subway to go shopping. Then they walked to one building named "Subway". The signboard of "Subway" was very noticeable and they could see it when the bus passed it every day. At that time they did not know it was a "store", for they always believed it was a subway stop. When they arrived there they walked around the store for half an hour, but they still could not find the entrance to go down.
Finally through making an inquiry, they came to know that "Subway" is a famous store of sandwiches. "Sub" is a short form of "submarine sandwich", which is a long thin loaf of bread filled with salad and cold meat or cheese.
Since then, whenever they pass by the "Subway", they can’t help laughing.
