Scheduling a realistic service sequence

A fictional salon has an appointment period of one hundred twenty minutes. Consultation takes fifteen minutes, the agreed hands-on service takes seventy minutes, finishing and client aftercare take twenty minutes, and required workstation reset takes fifteen minutes. These are supplied scheduling assumptions rather than universal service durations. A receptionist proposes fitting an additional fifteen-minute service into the same period by omitting the consultation and calling the workstation reset optional. The client also asks whether a photograph taken for the internal service record may be posted publicly. The exercise gives no local legal retention period, tax rule or licensing condition. The task is to evaluate the time model and distinguish consent for the service record from a separate public-use decision.
