The Internet has a wealth of information on Singapore, its attractions, customs, dos and don'ts and culture. When meeting a Singaporean he will generally exchange business cards with you. The proper way to receive a card is to receive it with two hands, continue holding it with two hands as you read it and exchange greetings with him. Keep your cards in your top pocket as it is considered an insult to pull a card out of your back pocket. For example, there are fines for jaywalking within 50m of a crossing, not flushing a toilet, spitting in public, eating or drinking on the MRT, buses or taxis, smoking in a public facility, chewing or bringing gum into the country.
Tap water is safe to drink.
