I watched for an hour. The club did brisk business, varied clientele but mostly male. They were checked at the door by a security robot that resembled nothing so much as a concertina'd octopus strung from the lintel of the main entrance. Some had to divest themselves of concealed items, presumably weapons, and one or two were turned away. There were no protests — you can't argue with a robot. Outside, people parked, climbed in and out of cars and did deals with merchandise too small to make out at this distance. Once, two men started a knife fight in the shadows between two of the expressway's support pillars, but it didn't come to much. One combatant limped off, clutching a slashed arm, and the other returned to the club's interior as if he'd done no more than go out to relieve himself.
