Theres a reason why the menu is so limited and its not just, as sociologists have argued, because the management wants you to eat quickly and leave. Its because McDonalds attempts to diversify all failed. Who can forget the Hula Burger (grilled cheese and pineapple), the Arch Deluxe (adult sandwiches with a secret mustard-mayonnaise sauce) and the McAfrica (beef and vegetables in pita bread), which was released during an African famine? Also, in an attempt to lure customers away from Dominos and Pizza Hut, there was the McPizza, which infuriated customers when they discovered it had to be made to order and consequently disappeared from menus.
