i mean there are so e floors for shopping,like one for cafe ,but what other like 80 floors are for ?
The former World Trade Center towers, plus virtually all of the other skyscrapers, are office buildings, providing floor after floor of space for companies ranging from small corporations, housed in a small suite of offices, to large corporations that may take virtually the entire building. It's usually only the ground floor that has services, such as restaurants, convenience stores, and the like. If you were to go to a random skyscraper and get off the elevator at a random floor, you would see a sign such as XYZ Importing Corporation, Suite 4201-4244 plus possibly a receptionist or a security guard restricting access to only those who have legitimate business there. Once you went inside one of the doors, you would see people at work at desks, either in cubicles or in private offices, reading e-mails, processing data, working on advertising graphics, people meeting in conference rooms--typical office functions. Remember that New York City is home to many of America's largest corporations.
