As with most countries, people in the service industry rely on tips, but this is even more important in Cuba. The average salary for a service worker is 12 CUC per month. As mentioned in our other guide on carrying cash, you'll want to have enough on hand to tip when appropriate.
Please be prepared to leave 1 CUC for every meal, every cab ride per person, and don’t forget the “entertainers”…musicians, etc that will perform for you just about everywhere. A daily tip of 1 CUC for your housekeepers is also a nice gesture.
