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.
You get shown where the hot water and teabags are, go do it for yourself, we’re all peasants in Sweden.
IKEA moment (yes, I also had a free cup of tea courtesy of my IKEA Family membership)
