Interesting piece from our friends at travelmonitor.com.au

Let’s not beat around the bush. Tipping is a pain. It is not so much about the willingness to tip – it’s knowing how much, and when it’s necessary. It can add unnecessary stress during your trips, and usually (for us inexperienced Aussies) it’s embarrassing.

To simplify the language of tipping for Aussie travellers, Babbelhas put together an ultimate tipping guide, from A to Z, restaurant to bar, to taxi.

Brazil

In a restaurant: a 10% tip is usually included on your restaurant bill. If not, feel free to add it.
At the bar: no tip necessary.
In a taxi: just round up the fare if service was good.


France

In a restaurant: a service fee is included, but you can leave some additional change if service was great.
At the bar: leave some spare change or round up to the nearest euro.
In a taxi: tips aren’t expected, but again, round up if you were pleased with the service.


Germany

In a restaurant: most people tip up to 10% for good service, depending on the meal. For lunch, round up to the nearest euro or 5 euros. For dinner, give 5-10%.
At the bar: it’s customary to leave an extra euro when you order a round at the bar.
In a taxi: if the ride was pleasant, round up to the nearest euro.


Greece

In a restaurant: some restaurants will round up your bill automatically — if they do, don’t tip any extra. If not, tip 5-10% in cash.
At the bar: round up.
In a taxi: tipping isn’t expected, but you can round up if you’d like.


Italy

In a restaurant: usually included in the bill, but leave 1-2 extra euros for good service. If not included, leave around 10%.
At the bar: round up to the nearest euro per drink.
In a taxi: tips aren’t expected, but round up if the ride was good.


Japan

In a restaurant, bar or taxi: tipping is not required, in fact you will cause embarrassment if you attempt to leave a tip. If you really feel you must leave a tip because service was especially good, do not hand over cash in plain sight. Put it in an envelope and make the exchange discreetly.


Spain

In a restaurant: tip 1-2 euros for casual meals and 5-10% for fine dining. Tip in cash.
At the bar: tipping for just a drink is not expected.
In a taxi: round up the fare if you’d like. If you tip, sometimes the driver will wait to make sure you get inside safely.


Thailand

In a restaurant: at casual restaurants, leave spare change on the table. At nicer ones, hand a 10% tip in cash directly to your server.
At the bar: not expected.
In a taxi: tipping isn’t expected, but most drivers will round up the fare.


United Kingdom

In a restaurant: some restaurants add a service charge to the bill. If they don’t, tipping 10% is fine. (The U.K. has a relatively high minimum wage.)
At the bar: tipping bartenders isn’t expected.
In a taxi: you can round up the fare or leave a couple of pounds for good service.


United States

In a restaurant: tipping 15-20% is expected at U.S. restaurants. (Servers and bartenders are often paid well below the minimum wage, often as low as $2-3 per hour.) Tipping by cash or credit card is fine.
At the bar: generally, Americans leave a dollar per drink or 15-20% of the total bill.
In a taxi: again, 15-20% is the magic number for tipping.
