Are You Being Served - S04 E03 - Forward Mr Grainger

When Mr Rumbold goes to Swansea for a month-long sales seminar, Mr Grainger is placed in charge, much to Captain Peacock's annoyance. Mr Grainger soon makes himself very unpopular because of the way he runs the department. However, very soon Mr Rumbold comes back as the hotel in Swansea has flooded and everyone ignores Mr Grainger.
