In American, you can't use "rubber" to refer to "eraser", you can't use "dummy" to refer to "pacifier", you can't use "bum bag" to refer to a "fanny pack"... In Australia, you can simply use "servo" to refer to a "petrol station", don't say you want to buy thongs in the UK or the US, they'll give you a piece of particular undergarment, very sexual, very seductive one....😏😏 Bunches of examples that are different amongst the UK, the US, and Australia... But I'm a Hongkonger, I love British English...
