They're there for the evening, not for a permanent stay. Most of the women pop by in a trance, take dick, then leave in a trance a short time later. If they're there for the full night then Lex somehow removed their need to sleep without causing them to go insane and die so it's safe to assume that only the permanent residents who aren't under device control get food and have access to the facilities. Someone as fancy as Lex probably has some kind of laser bidet or something.Do you think Lex has a good food menu for people in the cells? Also, I wonder if his bathrooms have bidets or toilet paper.
