Tip that is... at least in Australia.
Australia is a NON-tipping country. If someone does you a service such as in a cafe or carries your bags in a hotel, or drives you somewhere in a taxi, Australia has never been a country that tips for this sort of thing. Yet increasingly (and insidiously..?) its becoming more and more common and worse... expected.
Australians have always been paid pretty decently in the service industry, mainly because we've never had tipping. People get paid an hourly rate regardless of service or duties and its enough to get by on. But now, thanks to tourism, TV shows and the internet, people working in these fields expect you to cough up a tip as well as pay the usual cost of the service such as your coffee and cake in a cafe and get shirty if you don't pay the extra. I've had one cafe even put the 'tip' automatically onto the bill, and then give me an attitude when I demanded they remove it! I stopped the manager cold when he claimed that its to help the employees with their wages, to which I responded "What? Don't you pay them the (federally mandated) minimum hourly wage? I should report this place to the Workplace Ombudsmen", or words to that effect. Shut him up pretty quick.... Mind you I've never been back there a) because of the auto-tip business and b) undoubtedly my order would come with a 'some extra added saliva value' to it...
So, that's my tip for people coming to Australia... Don't. (tip)
