Usual rules of doing business in Indonesia:
Never ask a question to which the answer is yes or no - they will always try to keep you happy - thus not"is there any avgas at this airport?" but "how much avgas is there at this airport?"
Never, ever ever shout or rage - speaking quietly is the absolute norm
In Bali never touch anyone especially children on the head..
Smile, always smile...............
Go withe the flow - there's you and there are 264 million of them - they ain't going to change to suit you.
Lie back and enjoy it - and take a good book for the hours in lines, waiting rooms, offices...........................
