Tip those that provide a service, such as bartenders and servers, hotel workers, maids, drivers and tourist guides. Taxi and bus drivers also expect to be tipped, especially if they provide you with area information, such as where to eat or get a drink.
Tip in Cuban pesos. While U.S. dollars were once used to tip, Convertible Cuban Pesos (CUC) are now the norm. Exchange dollars for pesos and vice versa when leaving Cuba at a ratio of 1:1 at airports, hotels and banks.
Leave 10 percent when tipping, the standard tip percentage in Cuba. The standard 10 percent tip for most services, such as those from bartenders, servers and maids, is 1.00CUC, and 5.00CUC is standard for tour guides, according to Trip Advisor and Cuba Tourism's article on tipping in Havana. You won't necessarily have to leave a tip for maid or bar service every single day, for example, but tip every few days and leave a larger tip when checking out.
