Sometimes you just have to write…
The most typically Australian phrase is not “G’day, Mate,” as I expected, it’s “No worries!” It’s amazing how often we heard that phrase and in how many different situations.
Someone just gave you your change from a purchase. You say “Thank you.”
The reply: “No worries!”
You accidently bump into someone in the grocery store aisle and you say “Excuse me.”
You indicate you wish to get by someone on a crowded sidewalk or in a store. “No worries!” as the person moves aside for you.
“Could my son have mayonnaise instead of tomato sauce with his chips, please?”
“I’d like a tuna salad sandwich and a Sprite, please.”
