The Tollbooth: Violence Redeeming: Collected Short Stories 2009 - 2011 in Bloomington, MN

As the zombie apocalypse begins, a small group of civil servants find themselves locked in their tollbooths, which are heavily armored against run-away automobiles. Trapped inside their hellish fishbowls, they curse their situation. As they watch the world fall apart around them, however, they realize they are safe... for a time.
Cramped, dingy and institutionally depressing, their duty station becomes a backstage view of Armageddon. Even a bad day on the job is better than a good day amid a zombie apocalypse!
