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.
Germany, Austria, Sweden, Niederlande etc.
Excuse me what did you just call us?
Nah, I jest.
In all seriousness, thanks for adding the list.
I swear it’s not me, it’s my smartphone. We will have a serious conversation with it about this!
