It had been nearly a year since you won that labor lottery. This job had quickly turned into the best thing that has ever happened to you and your family. From the Grestin checkpoint, you had seen it all; terrorist attacks, long-seperated lovers getting back together, people trying to smuggle drugs into the country...
None of that compares to the day a portal opens to an alternate dimension just outside the walls.
Which is bad, because inevitably that means more papers for you to check and double check.
But still, a job's a job. Might as well keep a straight face about it...
And remember:
Glory to Arstotzka.
