Union Ministry of Consumer Affairs, Food and Public Distribution said "No hotel or restaurant shall force a consumer to pay service charge and shall clearly inform the consumer that service charge is voluntary, optional and at consumer’s discretion".
Customers can also lodge a complaint with the National Consumer Helpline (NCH), which functions as a substitute dispute redressal mechanism at the pre-litigation level by visiting their website or by calling 1915.
