An old school Ice cream shop that was quite popular in the neighborhood for many years, is suffering huge loss because of the opening of a nearby supermarket that hosts a variety of ice creams in their freezer section. The ice cream shop was once popular for their unique flavored ice creams but they are unable to predict the supply and demand causing many customers to get disappointed because they go out of stock every so often. The owner of the ice cream shop is your friend and asks you for advice to resolve this problem.
