Canadians struggle at times with the Aussie accent, especially if they are not used to it.
One day we were in a bookshop and I ask the lady,
"Do you have a book on the saints?"
She replied, "On sins?"
"No, on the saints," I repeated.
"Oh, on science," she said, and headed off in the direction of the science books.
Desperate to be understood I pulled out my fake North American accent, which had served me so well in the past in similar situations, and repeated my original question. To which she replied, "On the saints, I'm not sure. Let me check."
As an aside to this story, Bec asked another bookstore lady that same question two days later who thought she said science.
