Distinguish between the following: 'Contract of service' and 'Contract for service' under Consumer Protection Act, 1986

The Supreme Court in the case of Indian Merchants Association vs. V. P. Shantha, (CA No. 688 of 1993 decided on 13th November 1995) observed that a 'contract for service' implies a contract whereby one party undertakes to render services e.g., professional or technical services to or for another in the performance of which he is not subject to detailed direction and control but exercises professional or technical skill and uses his own knowledge and discretion. A 'contract of service' on the other hand implies relationship of master and servant and involves an obligation to obey orders in the work to be performed and as to its mode and manner of performance.
