9. The provisions of Sub-clause (f) of Clause (29A) of Article 366 need to be analysed. Sub-clause (f) permits the States to impose a tax on the supply of food and drink. The supply can be by way of a service or as part of a service or it can be in any other manner whatsoever. The supply or service can be for cash or deferred payment or other valuable consideration. The words of Sub-clause (i) have found place in the Sales Tax Acts of most States and, as we have seen, they have been used in the said Tamil Nadu Act. The tax, therefore, is on the supply of food or drink and it is not of relevance that the supply is by way of a service or as part of a service. In our view, therefore, the price that the customer pays for the supply of food in a restaurant cannot be split up as suggested by learned Counsel. The supply of food by the restaurant owner to the customer, though it may be a part of the service that he renders by providing good furniture, furnishing and fixtures, linen, crockery and cutlery, music, a dance floor and a floor show, is what is the subject of the levy. The patron of a fancy restaurant who orders a plate of cheese sandwiches whose price is shown to be Rs. 50 on the bill of fare knows very well that the innate cost of the bread, butter, mustard and cheese in the plate is very much less, but he orders it all the same. He pays Rs. 50 for its supply and it is on Rs. 50 that the restaurant owner must be taxed. ”
