Here are some etiquette for visitors to follow in order to be more accepted:
1) When entering homes, longhouses, mosques, temples and rural churches, shoes MUST be removed.
2) Appropirate dress is required when visiting places of worship. For example, when a woman visits a mosque, her head must be covered and she must be decently dressed (no short sleeves or shorts). For the man, he must not wear short sleeves or shorts.
3) When pointing at anything or anyone, use the thumb rather than the index finger.
4) Avoid handling food with the left hand; this is because the left hand is usually used for the toilets and it's considered rude and "dirty" to use the left hand.
5) When visiting someone's home or the longhouse even for a short while, it is considered rude to leave without first having a snack or drink when offered by the host/hostess.
6) Public displays of affection (kissing, holding hands, etc.) are usually frowned upon, and nude bathing or topless sunbathing in public areas (beaches, etc.) are NOT acceptable at all.
Miri runs on a normal eight-hour working day system with Saturdays as a half-day workday and Sunday as a day of rest.
All public service departments and some banks usually close on the first and third Saturday of the month.
Private sector hours are generally from 9am to 5pm (Monday-Friday) and 9am to 1pm (Saturday) while government office hours are usually from 8.30am to 4.30pm. Many private sector companies operate on a five-day week.
Most shops and shopping malls are open from 10am to 8pm (Sunday-Friday) and from 10am to 10pm (Friday - Saturday).
The custom of tipping is not practised in Malaysia. To tip or not depends entirely on you.
Most hotels and large restaurants have already included a 10% service charge in addition to the 5% government tax to the bill (indicated by the ++ sign on menus and rate cards) so tipping is unnecessary.
However, if you are happy with the services provided, say in the restaurants, it is no harm tipping the waiters/waitresses (usually, they are paid low salaries and they will be happy to get some extras).
Nothing much to worry.. we shake hands, hugs(make sure she/he is comfortable with it, not applicable to all ok!) and the cheapest or easy way to greet is to SMILE :-)
