After learning that a trio of hotel inspectors are doing the rounds in Torquay, neurotic hotel owner Basil (John Cleese) comes to believe that one of them is a guest at Fawlty Towers. At first he suspects pernickety and obnoxious guest Mr. Hutchinson (Bernard Cribbens) of being an inspector, and does his utmost to keep him happy, but when Sybil informs Basil that the man is just a spoon salesman, his attention turns to grouchy Mr. Walt (James Cossins).
Watching Basil fawn and squirm is absolutely hilarious, as is his inevitable meltdown, when the desperate hotel owner offers Mr. Walt cold hard cash to keep quiet. Nothing, however, beats the very ending, which sees Basil welcoming three new guests (the real hotel inspectors) having just given Hutchinson a well-deserved send-off with a couple of cream pies and a jug of milk. Cleese's reaction is priceless.
