If one or maybe more worker can not come to work, the program then automatically pick randomly another worker from an existing array, who are not currently working the same shift and replace into that position. The payment then also is made to the person who works the shift. Workers with many sick leaves will be fired and worker from a list of unemployed will be chosen to replace the position.

Customers have their own choice of food by the random numbers used in the program. Also the amount of food that they order is related to their hungry status. Along, customers can make complaint if they become sick because of the food they bought or because the food is not available at the time of order.

Each type of food in the program has its own expire period. After the period, the food is thrown away, number of food in stock will be deducted and also the decreasing of revenue as there are expenses that the restaurant has to pay for the non-selling food.

When fire, robbery or even bomb and earthquake occur. The restaurant will result in the lost of property or cash and probably complaints from customers and hence more money have to be spent to cover the lost, or improve the condition of the restaurant. This could lead the restaurant to a bankrupt and closing down of the business.  After a emergency, the number of complaint would be increased significantly.

The compensation will be paid for the customer if there are too many complaints.

There are three types of insurance  that we can choose to buy. With insurance, we will receive compensation when the restaurant is damaged. The amount of compensation can be different depends on type of insurance.

Another interesting thing is about the Graphic User Interface of the system. The whole program is displayed in a panel. The quantity of food in stock is displayed by bar graphs. When the food quantity runs low, a warning message is displayed. A text pane displays the financial statement and other information. When the store's profit goes negative, the text pane goes red, and food prices are increased. When profit goes high, food prices are decreased for customer satisfaction and the text pane goes blue.
