Hall of Infinite Doors

The hallway widens here, the nondescript (or previously descript but not having done so in a while newly-nondescript) floor mottling and changing until it's composed of thick grey asphalt. A yellow stripe springs up down the center, and two ribbons of sidewalk materialize along each side.

The hallway acquires something new here: a tollbooth. A stern-looking individual with a donut and a rocket launcher sits inside, wordlessly daring you to try and sneak past. A wide yellow bar cuts off access, and a big white sign spells out "PAY TOLL 3.50$" just above.

Of course, there are several means of egress apart from passing the tollbooth, but considering the nature of the hallway who knows where they'll go.
