Olivia Ellor-Freeman and Lydia Kortey are the Serco caterers on my ward. These two, along with their cleaning colleagues, are lovely and always uplift the patients, if not with Serco food, with their presence. I love the way Lydia ignores our illnesses and, if someone is asleep when she is taking lunch orders, demands that they be woken up. My message to their grossly overpaid Serco CEO - 'Their wages, hours and conditions are shocking. How do you sleep at night?'
