Snack Foods, Investigated

While out drawing on-site with my students the other day (trying to encourage the "sketchbook habit," don't you know), my own entry included the following.

Or, maybe just the mundane, banal musings of an illustrator on the loose in a town with a Subway, and not much else. Enjoy?
