Well, that went surprisingly well.
Sorry for the lateness of this update ... one, I was away last weekend on a camping trip with friends, so I got a late start, and two, it's hard to draw other artist's characters, ya know? If you don't recognize the barista, I suggest you go re-read Shaenon Garrity's Narbonic (you have read Narbonic already, haven't you?) As for the customers in the last panel, you can find them (if you are very sure that you won't be offended by strong language or adult situations) at Questionable Content, by the awesome Jeph Jacques.
I figured the coffeehouse needed a little artwork on the walls, so I gave it a print of the piece I did for the Web-Comics Auction for the Gulf Coast. There are some excellent contributions for sale, and all the money goes to a good cause, so check it out!
I drew the last panel while sitting in the local coffeehouse. It just seemed ... right.
