Indonesia has several traditions and customs and it is best if you know them beforehand. Some of them are:
Even though hand shaking is deemed appropriate between men and women, bear in mind that a number of Muslim women prefer to introduce themselves to men by nodding their head, smiling, and clasping their hands without any physical contact.
Traditionally, when you greet someone, both hands are used when shaking, without grasping.
It is considered polite to make a phone call first before visiting.
Shoes must be taken off before entering a house or places of worship like mosques.
Usually drinks are offered to guests. It is polite to accept.
When eating, receiving or giving something, always use your right hand. Your right index finger should not be used to point to a place, item or person. Instead use your right-hand thumb and fold the remaining fingers to be more polite.
Taking photographs of houses of worship is allowed. However, permission should be requested first whenever possible, especially if you want to take pictures of the interior.
Most Indonesian Muslims do not consume alcoholic drinks or pork.
Hence, the tradition of proposing a toast to honor someone is not generally known.
