It works like this. You order 2 cups of medium tea. You bring your travel mugs. You take a lot of Splenda. You pour your tea into the travel mugs. You go back and have them refill your empty cops. 4 cups of tea for less than 3 dollars.
If you order a large size to begin with, the tea will be too weak. Regular cup filled twice is perfect. And the Higgins and Burke Earl Grey tea is very nice.
This ensures that when you go to the movie you will have to pee at least nine times. But at least you get your money's worth on the tea.
