Basil the Rat (a.k.a. Rats) - S2-E6
Corrected entry: When Mr. Carnegie is running through the list of things he has found wrong in the kitchen, one of them is the lack of a wash-hand basin. However in the episode "Waldorf Salad" Terry is seen washing his hands in the kitchen sink (wash-hand basin) and in this episode when Polly closes the fridge door the sink is visible. So why is Mr. Carnegie complaining about the lack of a wash-hand basin when there is one already present?
Correction: Perhaps he considered just one not enough for the size of the kitchen, thus a "lack" of hand wash basins would be correct.
