The restaurants may be asked to mention the actual price of a dish including taxes and other charges payable by the customer. How the establishment accounts/ computes the amount that is to go to the Government and to the establishment is a simple internal exercise (a software fix would do the job) with which the customers need not bother about.
Some restaurants levy a separate Service Charge which is normally about 10% of the prices mentioned. Is it the cost of Cooking? Waiting? Cleaning? Space? Air conditioning? etc etc. If payment of service charge (the new term for Tip) is compulsory and not a matter of choice, it should be included in the price of the dish. I wonder whether the amount collected is at all paid to the service staff or simply pocketed by the establishment!
A change in existing practice is called for in the best interest of Customers and also the Government more
