Giving a tip is something to show appreciation and gratuity for rendered services. The people of Curacao truly hope you will tip well, for this will mean you love your stay on their island! It is suggested to tip the porters at the airport  USD $1 per bag. Taxi-drivers are usually tipped with 20% of the fare. Restaurants usually add 8-15% service charge on a bill, and most hotels a 12% service charge to the bill. Hotels charge an additional 7% government tax. Not all restaurants charge a service charge, so check your bill before you decide to leave a tip. Managers of restaurants confirmed recently that the "service charge" on the bill is mostly a tip given to your server, with the rest going to the establishment and split among all the workers.  Rule of thumb: most of the "service charge" on a restaurant bill is really a tip.
