I thought it was pretty funny. The hat was for some sports team the barista apparently didn't approve of, and the burn slam was pretty unexpected. Those two, another barista and me got a good laugh out of it.
Following the Starbucks theme, this other drawing is just one I did the other day on one of the Starbucks rewards brochures. Dori and I were hanging around down town and I didn't have any paper with me. I don't know what this guy's problem is, though. I'd like a free drink.
