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.
Either you’ll get a sweet iced tea, or they’ll ask “sweet or unsweet” before bringing iced tea.
Durham, North Carolina here.
Yeah. I’ve lived in rtp for a long, long time.
It is very, very rare that you get asked that question. Extremely rare. That’s kinda the point of this post.
