Exam

They serve raw food products, such as meat, pork, meatball, and vegetables, for customers to cook as Sukiyaki at their table and a wide range of alacarte, such as roasted duck, dim sum, and sweets. Basically, there is no food stocked at each restaurant. Both raw food and pre-cooked alacarte are prepared at factories located at each province and then they are delivered to the restaurants every morning. Each restaurant has different size; therefore, amount of food to be delivered is not equal. Because eating habit of people is different from one to another area, the estimated amount of food on each day in week is not necessary to be equal; for example, people in office area will go to restaurant during day time and people in living area will go during weekend.

In the company organization, there are two positions that are responsible for food stock: provincial manager and country manager.
