Everyone in my (American) family drinks at least a cup, and often 3-5 cups of tea per day. This is considered a lot here. Tea drinking is so non-normalized that despite my entire family's love for tea, I was well into adulthood before I learned of electric kettles (from Tumblr) and introduced them to my family.

They're easier to find these days but still rare. If you ask for a hot tea at a restaurant, you'll often get a suspicious-looking teabag that has spent at least 6 months in the cupboard (iced is more available). I'm sure you can guess at the quality of most of the teas in an American grocery store; I usually wind up ordering from specialty tea shops instead.
