Tony and Bren arrive early to the canteen in much better moods than usual. Unfortunately, everyone else is in a bad temper. Stan has had trouble with his father, Dolly and Jean bicker continuously, Anita is convinced her new haircut makes her look like Fatima Whitbread, and Twinkle thinks she is pregnant. Philippa suggests having a "Bring Your Mother To Work" day to cheer everyone up, though Dolly's sarcastic mother Enid (Thora Hird) and Jean's ymphomaniac mother Connie (Dora Bryan) do little to raise the workers' spirits. Stan brings his father, Jim (Eric Sykes) and Petula arrives with an old lady who she says is her own mother.
