Tipping:
Tipping with ones for the hotel porters is useful. Tipping for guides are on average 10 – 15 US/day and drivers about 5 – 10 US/day. Tipping is not expected only if they do a good job then you can tip as you feel. Tipping in restaurants are not expected either. But if the waiter provided good service then you can leave a tip in local currency of about 1-2 USD. Local food stalls along the road you do not need to tip. Usually only in sit down A/C restaurants if good service is provided.
