Ronnie Barker stars as Arkwright, the tight-fisted stammering shop-keeper, who would rather risk instant amputation than replace his death-trap of a till. A young David Jason plays Granville, Arkwright's ill-fated, over-worked, sexually-frustrated errand boy, while Lynda Baron is Nurse Gladys Emmanuel, the owner of an awesome bosom and an old Morris Minor and is the object of the grocer's undying lust.
