Public gestures of affection between man and woman is not common in Nepal. Therefore, avoid such affection in public.
Drug abuse and drug trafficking are strictly followed. Possession of drugs is a serious offense in Nepal and will be severely punished!
Alms create more beggars, but not solve the underlying problems! For these reasons, you should not encourage beggary. If you really want to do good, ask your tour leader/guide then and donate money to a school, an orphanage, or other means, but not to street beggars (even if ever so enterprising stories dish!)
Use the hotel safe for valuables. Do not leave money or valuables in the room are open.
