Annoying ways to start your Monday, part one:
Walk into food/coffee selling establishment. Find no one behind counter. There is someone nearby, mixing something in a blender but he's got his back to you. It's very loud (due to the blending). Wait. Wait some more. Hear the phone ring. See guy come from back/kitchen area to answer phone. Wait. Still noisy. Notice that the blending guy still has his back to you. He's focused on that blender like he's monitoring a gas spectrometer. Note that guy on phone has put down phone. Assume he's going to take your order. Stare slack-jawed as he disappears into the back without ever acknowledging your presence. Note that the blender operator is still blending away madly and has also not turned around, rendering him incapable of acknowledging your existence. Leave. Leave quickly to avoid temptation to wonder aloud why the fuck they don't want you to spend any money in their putative food/coffee selling establishment.
Go somewhere else.

My advice: don't go to Nosh for your morning cup of coffee.
