In the South East, they bring you sweetened (usually far too sweetened for my tastes) iced tea. This is amazingly universal.
I live in NC and have been probing the border for years.
For “nicer” restaurants, the universal sweet tea boundary seems to be precisely at the NC/VA border.
That’s okay, I’m an American and interpreted South East as South East Asia too.
I don’t normally see the space when referring to the Southeastern US, only for South East Asia. I have no idea why that is and have never really thought about it.
