When eating out in Croatia, if you have enjoyed your meal and are satisfied with the service, it is customary to leave a 10% to 15% tip. It is not usual to tip in cafés or bars. Housekeepers and taxi drivers are not usually tipped. Tour guides do receive a tip, especially if they are particularly good. For porters on trains and bellhops at hotels, 5 Kn to 10 Kn per bag will be appreciated.
