Ok, I loved my customers when I worked at Starbucks, but I can't pretend to not be at least slightly bummed that no one ever did this for!
This, my friends, is a very intricately drawn rendition of the map of Middle Earth. On a Starbucks cup. Just abandoned there, for anyone to find!
I don't know about you, but I think this is pretty awesome. What would you want to draw and leave on a cup for a barista to find? I think the most exciting thing I got was a "Thank you!" scribbled on a cup.
