Most of the hotels and guest houses in Burma charge in US dollars. They may also accept kyat but usually, at disadvantageous rates. Some government ferry clerks, shops and hotels may give change in the currency of kyat or with the torn US bills which are unusable elsewhere in the country. If you believe in counting pennies, then it would be wise for you to bring small dollar bills with you and use them for paying for your hotel.

Government run services like archaeological sites, ferries and museums and flights are usually paid in US dollars or in FEC notes, but not in Euros. Items like bus tickets, taxi rides, water bottles, beer, trishaw and meals are usually charged in kyat.

You cannot expect to change rumpled and torn US dollar bills because moneychangers only accept clean and crisp bills. Usually, bills with CB as their starting serial are turned down because they are old.

Officially, tipping is highly discouraged but it has become a common practice now and it is OK to reward fine service. Usually, the same guide and driver will accompany you throughout your trip to Bhutan and though it is officially not legal, most of them expect some tips at the end of your trip. Many group tour participants can collect tips at the end of the trip and hand over to the guide or the driver in a single packet. If your group is large enough, the amount of the tips can be big enough.

If you are trekking, then it is perfectly appropriate to give tips to the waiter, cook and guide. Horsemen may also expect some tips but this is not needed if they are the owner of the animal or they have hired out their horse or yak. Tips can also be given to people if they have helped you on the trail or in the camp chores.
