Use your judgment
“Even though tipping in Cuba is not as customary as in Canada—and by no means an obligation—it is much appreciated to tip hospitality workers when you have enjoyed good service. Tipping is entirely at your discretion, but here is a guideline: hotel porters 0.50 CUC per bag, maid service 1 CUC per day. In restaurants: 10-15 per cent of the bill (but do check if it is already included on your tab). During excursions and tours: chauffeur 2 CUC per person, per day and guide 3 CUC per person, per day,” says Cuba Travel Network‘s general manager, Karen Esposito.

Tipping in Thailand is appreciated, but try to give your tip directly in cash to your restaurant server, massage therapist, or tour guide to ensure it’s properly received. “Although most taxi drivers don’t expect a tip, many will round the fare up to the nearest baht,” says Bisesto.

In Australia, tips are taken—but they aren’t always necessary. “Restaurant prices must include taxes and service fees, alleviating the need to round up when leaving a gratuity,” says Bisesto. When staying at hotels, tipping the concierge or front desk staff is unnecessary, but you should consider giving the bellhop a few dollars if they help carry bags to your room.
