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.
In my experience they don’t drink coffee either, rather than over-roasted bitter tarmac
I’m watching my spending and figured I’d buy the “fruity light roast” from the grocery store and it tastes like what I imagine drinking an ashtray would taste like.
From someone who once drank an ashtray on a pub bet, I’ve definitely drank some worse coffees.
