The official currency is the Trinidad and Tobago dollar (TT$), but many goods or services are priced in US$. We quote rates as they are given, be it TT$ or US$.
Tipping has not traditionally been part of Trinidad and Tobago culture, though it is increasingly common.
Restaurants Many restaurants add a 10% service charge to bills; if not, a tip of 10% to 15% is customary.
Bars High-end or tourist-oriented bars may have a tip box on the bar; it's up to you if you want to contribute.
Chambermaids It's usual to leave TT$100 or so at the end of a stay.
Grocery stores If packers bag up your shopping, wheel your trolley to your car and pack it into the vehicle for you, give a tip of TT$5 to TT$10.
Taxis Don't tip maxi-taxi or route-taxi drivers. Tipping private taxis is not expected but will be appreciated.
