Pardon The Expression (Season 2 - Ep.7) The Big Hotel (1966)

First broadcast: 21st Feburary 1966

Plot (from Corriepdia):
Leonard Swindley and Wally Hunt are in London for the purpose of exhibiting Dobson and Hawks dressware at a trade fair at Olympia. Mr Hunt has told his beloved wife that such visits are hard work and far too strenuous for her, meaning that he intends to enjoy himself in the capital. He orders Swindley to obtain two models for the clothes - by which he means plastic dummies - but Swindley assumes he means catwalk models and the willing porter of the hotel, used to helping with such requests, gives him the telephone number of a callgirl agency in Mayfair. Two girls, Dawn and Samantha, are sent along to Swindley and Hunt's hotel rooms. Things look bad but get even worse when Mrs Hunt turns up, concerned for the stress that her husband will be suffering over the trade fair. Hunt passes off the girls are Swindley's affair and the little man, somewhat out of pocket, is beleaguered by the girls for their fees...
