It was Jeremy Lloyd who came up with the title "Grace & Favour" (a pun on both Grace Brothers and also the term for premises which have been granted free of rent). His co-writer David Croft had wanted to call the series "Are You Being Served Too?"
Trevor Bannister, who played Dick Lucas from "Are You Being Served?" Season 1-7 was asked to reprise his role for this show but he turned it down.
Mr Rumbold actor Nicholas Smith much preferred the broader scope, bigger budget, location-work and what he perceived to be more layered scripts of this series to the parent series Are You Being Served? (1972).
