For those learning Australia English and customs: I was standing at a deli counter in Queen Vic Markets and hear some people next to me asking "Is this place any good?" and I reply with "Oh no. It's terrible. You don't want to shop here." but with a big grin on my face.
To Australians, this is a ringing endorsement that the place is actually very good and you should definitely get something from here. But I imagine to those who take the words literally, they might be confused as to why I was shopping there if I thought the place was so terrible and also they should go elsewhere. š
Welcome to Australia.
