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.
Netherlands: you get asked what kind, or hot water with a box teabags to pick from.
Iced tea is a seperate thing entirely.
Ordering tea and getting hot water and teabags in return is my restaurant pet peeve. It’s gotten to the point where I don’t even bother unless I know they’ll actually bring me a pot of already-brewed tea.
You’re getting downvoted, but I can relate (even if I never drink tea while out.). It isn’t much work to let it steep, then take the tea bag out, but it’s not about the literal work, but the brain energy involved. My short term memory is trash, so I often forget about drinks; I had to learn to enjoy lukewarm or cold coffee, otherwise I would rarely drink coffee.
For me, the water is always too cold to properly steep tea from by the time they bring it.
