Single Mocha

Every day between 3 to 4pm I take the elevator all the way to the lobby of the office building to get my mocha. It's been like this for the last few weeks that I dont need to tell the barista what I want, as soon as she sees me lining up for coffee she starts making my single mocha, I also know how much it costs exactly with taxes, so I am ready at that end. Quick transaction without even uttering a word.
