Lucas planned to sign in and out 'sick' for a hot date, but Grace Brothers has strict rules and Peacock enforces them with military rigidity, and the onion and soap tricks Mash suggests are known as well as poorly executed, so he only incurs a negative examination by the shop nurse, who finds Slocombe's cold, which scares Brahms, bad enough, but she refuses to miss out on commissions, rather 'self-medicating' with hidden brandy. Peacock allows Brahms to swap sections with Lucas, who now has to handle a frisky lady customer ALterantins play the lead in tricking customers into unfit purchases. Humphries arrived crooked after a bad yoga exercise but soldiers on, while Grainger has to dash off to the loo almost constantly. Mash's last resort for Lucas, falling over soap, has an undesired effect as Mr. Grace arrives.
