Note to self:
When you have two back-to-back half-hour meetings called "Meet for coffee," do not actually take that literally.
Also, when barista sees you for the second time in half an hour and you ask to please refill your cup rather than waste a new one, and she asks, "do you maybe want a double this time?" the correct answer is "no."
