Singapore: Not customary; in fact, Singaporeans become upset when they see tourists tipping. The one exception is hotel bellhops, who are usually tipped 1 Singaporean dollar per bag.

This has not been my experience in 20+ trips to Singapore.
1) Bellhops do not expect a tip, but neither do they refuse one
.
2) Most restaurants already add a 10% service charge on the bill. Singaporeans do tip if the restaurant does not although not much; a Singaporean colleague once recommended to me to give a 50SGD tip on an approximately 950SGD restaurant bill.
