Question

In a very famous Option restaurant, they followed a specific system to speed up the preparation of meal. The manager provides table to the customer either directly or by call reservations. Each table assigns a number plate when it is reserved. A device is place in the table. It has three functions i.e. Call, Take Order, Pay Bill. If we press Call button then manager comes to the assigned table to resolve any issue regarding seating. If we press Take Order then waiter takes order in a Notebook (a list of dishes and drinks ordered by the diner or group of diners). Waiter must know that dishes that have been ordered are available or not. The system must confirm the availability of dishes. If the dish not available then waiter should ask to change the order. Dishes to be prepared are sent to the kitchen and drinks to the drink bar. Starters and main course orders are usually taken together. Drinks and desert orders may be taken separately. If we press Pay Order then we can pay our bill as cash or by credit card to the waiter. The system also keeps track of the numbers of customers served by each waiter management can view these statistics.
Kitchen staff sees the dish orders on their screen and then prepare them in a proper sequence and confirm preparation to the system when complete, similarly with the bar. The Restaurant is open for 24 hours to serve the customers, for this, the owner of the Restaurant wants that system should remain available all the time. Also, he has some concerns regarding payment transactions from customers using the system. When a waiter sees the completion indications on his terminal he collects the item and then serves to the related table number.
