This past Saturday morning, I boarded the Blue Line train to Largo at Pentagon City and saw this sleeping passenger across the aisle from me.
He had taken his belt off and tied it to the hand rails on his seat and the seat in front of him.
I wasn't sure how to interpret this makeshift barrier: Velvet rope? Crime scene tape? At any rate, this passenger awoke a few stops later, untied his belt, exited the train, and proceeded to re-loop his belt onto his droopy pants on the train platform.
