And what is more there is virtually no justifacation in even thinking about tipping in Sydney ....

If you enjoy the fawning "hi I'm Heather and I'll be your wait-thing for this evening" type of rubbish service you'll be disappointed in Sydney dining. What you get is pleasant people serving good food in an efficient manner, and they're paid a living wage by their employer.
Always happy to fuel FT's fetish for pedantry.
