Thank you."The upstairs lounge was not at all grungy. It was wall-to-wall carpeted in oyster gray. The walls were an eggshell white and hung with plesant nonrepresentational prints. A steady, soothing progression of colors met and swirled on the ceiling. There were one hundred couches in the large room, neatly spaced in rows of ten. Five Jaunt attendants circulate, speakingin low, cherry voices and offering glasses of milk. At one side of the room was the entranceway, flanked by armed guar
