Canteen manageress Suzy seems to be favoring Jack and Stan over Blakey and giving them considerably larger portions of food than him so he gets rid of her and replaces her with the austere ex-prison officer Gladys. But she too has needs and when Stan tries to charm her in order to get extra food he discovers exactly what they are. Eventually Blakey gets rid of her too and installs a vending machine.
