It was a round high-ceilinged space, with registration kiosks, lots of corridors leading off toward the room sections, and an archway into another room with shelves and cold cases where food products were stored for the humans staying in the hostel. (Or really, for any humans or augmented humans who wandered by. The Preservation Alliance has a weird thing about food and medical care and other things humans need to survive being free and available anywhere.) The bot was in there, restocking items from a floating cart.
