On a domestic flight from Sydney I had this exchange with a newly arrived U.S. visitor to Australia a few years back.
Me: Madam, would you like a cup of coffee?
Passenger: Do you have any tea with yee?
Me: I'm sorry, I'm not sure what you mean by yee.....
Passenger: Oh..... no I'm sorry, do you have any tea with thou?
Me: Are you trying to speak olde english?
Passenger: Isn't that how you speak here in Australia?
