Indonesia shares the same attitudes to dress and social taboos as other Southeast Asian cultures. In addition, Indonesians are generally very sociable, and dislike doing anything alone. It’s normal for complete strangers engaged in some common enterprise – catching a bus, for instance – to introduce themselves and start up a friendship. Sharing cigarettes between men is in these circumstances a way of establishing a bond, and Westerners who don’t smoke should be genuinely apologetic about refusing; it’s well worth carrying a packet to share around even if you save your own “for later”.
