@nprofile1q... why in the world would you have coffee delivered when you could "take a break" from whatever you're doing staring at a screen, walk to the shop, stand in line and chat with people, order, and casually walk back to your desk? That's why it's called a coffee break.
Sometimes the little grey cells need time to relax. And the Great Machine that is the Subconscious mind can think on whatever you're working on in the background.
