The mall was open 24 hrs of course but, as had always been the case, there was a rhythm to the day. The systems that ran and staffed the Mall might not have a life but the human customers still slept and some even had fixed work hours. She liked the early evening. She particularly liked the shops that had invested in a human assistant. She felt special when a real person checked the recognition feeds and smiled at her. She loved watching the prices change. She sometimes sneaked a look at another customer’s prices, someone whose face didn’t fit.
