Olivia was still very much absent minded as she made her way home.
Her manager had sent her home after all. Turns out the two strangers she had seen standing beside the manager, were customers. They had entered the restaurant earlier than the manager. They had called out to Olivia severally, but she had been too absent minded to hear them or answer. The customers had become troubled as they stood there, watching Olivia move around the space like a zombie, and they were about to dial the police for help, just before the manager walked in.
