PURPOSE:To perform good services by adding service information discriminating waitresses via a magnetic card to the information on dish names which are requested by customers with operation of menu keys and displaying the average waiting time needed for ordering through waiting for each menu. CONSTITUTION:The time point when an order key 4 is operated is counted and the order of a customer is urged in an interactive style via a display part 5. When the customer operates a desired menu key 5 for selection of dishes, this selection time point is counted and stored for each dish. Then the customer pushes a confirmation key 4b and a key-operable state is set again. When a card is put into a magnetic card reader 3, the codes discriminating waitresses are read and a time counting action is performed. Then the average waiting time needed for ordering through waiting is calculated for each menu. These times are averaged and totalized for each dish and displayed on a display part 6 as necessary or by request of the customer. Thus the numbers of tables served and the service time points are totalized for each waitress. |
