ATMs widely available; carry cash as backup, especially in remote regions. Don’t accept damaged banknotes: they won't be accepted by others.
Restaurants and hotels Service fees are sometimes added to bills automatically; otherwise, 10% is reasonable.

Taxis and rickshaws Not expected, but it's good to tip drivers/riders who are honest about the fare.
Private drivers ₹200 per day for good service.
Trekking Per day guides ₹350 to ₹500, porters ₹200 to ₹350.
Tour guides ₹200 to ₹350 per day is fair.
