Don't you get it? This is Australia not bloody yank land... Some people..
Not just a "YANK" thing
The tipping culture is also in Europe, though not as "compulsory" as in USA, but more so than in Australia.
I've heard of Australians not learning about, or adhering to the European country's tipping(gratuity) customs, only to have their luggage disappear as the untipped taxi driver disappears over the horizon.
You go on any cruise ship and you are politely notified of the expected tips, an overflowing toilet can unexpectedly occur if you dare to be non-compliant. You also don't know what the staff do to your food when you have room service delivered if you are branded a cheapskate non-tipper.
This is probably the only country in the world where the staff serving your food on a Sunday/Public-Holiday can be paid $50 per hour due to our unique "penalty rate" system.
When in Rome.....
Tipping in Italy Taxis
It is not common to tip taxi drivers in Italy, but if you wish to tip your extra nice driver he/she really won't mind. For a great service it is easy to round up the taxi fee to the nearest 10 or 5, and offer a small tip for your taxi service. If you haven't received a good service or feel you have been ripped off, you do not have to tip.
