What to tip: Australians don’t expect tips. No, really. The wait staff Down Under are paid over $20/hr, and they basically get an eternal summer, so don't feel bad for them -- although you should be prepared to beg for a glass of water and have to ask for your check multiple times. On the rare occasion you encounter decent service, round up the change.
That means: Order a couple Little Creatures drafts at The Australian's bar in Sydney for $12.50, and leave $13 without feeling like a heel.
What to tip: Like so many things here, tipping is fairly formalized; service will be included in the bill if expected, and if it isn't, keep the change.
That means: Your meatballs with cream sauce, gherkins, and lingonberry jam at Stockholm's beer hall/ resto Pelikan may set you back 192 krona; leave 192 like the good people ask.
