The school is in the UK, and Scotland at that - barely anyone has health insurance. The system uses face recognition for interactions at the till, when paying for food, the likelihood of it filming usable footage of the dining hall that will be kept until leaked is pretty low. A more likely threat model is that rather than video analysis, the system records Tommy bought five doughnuts each day and that database get leaked/sold.
