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 Israel you’ll get a cup of hot water and teabags to choose from.
Hot water with peppermint is also a popular option as well as sweet tea.
