<Li> Dennis Waterman as Tony Carpenter, the lead character, owner of a luxury car hire business in the Surrey "Stockbroker Belt" and ardent supporter of Charlton Athletic . Although he's proud to be a "self - made man" and enjoys the good life his success has brought, Tony is unashamed of his working class roots and treats his staff more like friends, to the frustration of his wife . </Li> <Li> Sam Kelly as Sam Jones, a friend of Tony since their days at Clapham Parochial School . An ex-Merchant Seaman, Sam was the first driver he ever employed, and now works as chauffeur to the Carpenter family . Although Tony is his boss, Sam still behaves more like a friend towards him and isn't afraid to criticise his behaviour . Sam has feelings for Maggie but believes she prefers Tony; however, in the final episode the two get together . </Li> <Li> Joan Sims as Mrs. Fiona Wembley, the Carpenter family's cordon bleu cook . She is something of a confidante and mother figure for the others in the house and becomes upset if Tony isn't eating properly . Fond of sherry - leading to her largely inaccurate catchphrase "just the one" - her tippling is indugled by Tony; when she fears the sack because Ruth is returning home, she confides in Sam that she worries another employer wouldn't be so understanding . Late in series one it's revealed that she never actually married Mr Wembley, as he was killed in the Korean war before they could . </Li> <Li> Jenna Russell as Maggie Lomax, a young Scottish secretary of strong socialist leanings . She is highly efficient and regularly saves Tony's bacon when things go wrong . She and Ruth make no secret of disliking each other, something which largely stems from Ruth's (accurate) suspicion that Maggie has feelings for Tony . Maggie later gets over Tony and starts a relationship with Sam in the final episode . </Li>
