The excessive waiting lines create some major problems in the everyday life. It also affects the productivity of the organization that will in turn affect its revenue. Some of the examples of the waiting line can be seen in the Quick Service Restaurants (QSR), pharmacy and in the retail stores. Among those QSR is one of the sectors that hurts most by this phenomenon as the customers of this industry expect to receive their order comparatively a faster way. So, a long waiting line reduces the demand of the organization among its customers (BROX, 2010). Also, when a consumer planning to buy regularly from a particular restaurant, then the person prefers a restaurant with a shorter waiting line.
