To the Oppositional Defiant Adult at Caribou-

Dear Sir, when you walk in the door and the workers recognize you and ask "Would you like your usual, Sir?"  This is in attempts to make your services quicker and speedier, not to make you think they, the workers, are stalking you.  There was absolutely no need to sarcastically ask back, "Oh, What's my usual order?"  And then intentionally order something completely different.  If you want to remain autonomous and anonymous, don't go to the same Caribou every day.  You have other options, and if you don't like that... make your coffee at home.
