The less famous, the less returns. I know franchises like McDonald's are expensive but they bring with them rush of ready made customers and we don't need to advertise. I remember the first McDonald's opened in Karachi did a business of 4 million rupees in its opening day. That must be like 10-15 years ago.
We have got first Burger King here in my city of work and I see rush of people everyday since its launch.
