American/Australian
Note that some of these may be localised things as I spent most of my time in TN and SC, just as there are differences between east and west coast of Australia.
1. peppers/capsicum (e.g. at Subway).
2. to go/takeaway (e.g. at McDonalds)
3. here/eating in (e.g. at McDonalds).
One of my first experiences was when I went into Santa Monica McDonalds in California, made my order and they said real fast; "will that be to go or here?"
Fortunately I remembered a line from the Twister movie (and other movies) where they said things like; "can I have two coffees to go",and I caught on to what they were asking.
4. gas/petrol
5. truck/ute
6. buggy/trolley
[for example I had an embarrassing episode when the checkout operater says "can I put that in your buggy" (I didn't have a clue what she was saying!..especially as I was struggling with the accent anyway *LOL*) at a checkout in Walmart.....Walmart is a bit like K-mart and Coles rolled into one.]
7. cookies/biscuits
8. candy/lollies
9. toboggan/beanie
10. sweatshirt/jumper
11. britches/long pants,jeans etc.
I think this one is more a VA/TN or southern thing perhaps.
12. cellphone/mobile
13. physical therapist/physiotherapist
14. ketchup/tomato sauce
15. zipcode/postcode
16. yack at ya/talk or chat with you.
17. peanut butter/peanut paste
