I’m surprised to hear it’s that high in Australia. I just got back from the US and it’s awful over there.

The last two times I remember tipping in Australia (excluding “keep the change”) was one for a local food truck I like during the pandemic lockdowns. The other was a few years before that at a restaurant after I told them we were there for my mum’s birthday to get a candle in the desert, the chef instead took her back into the kitchen and showed her how they prepared several of the dishes (and we got the candle).
