It is revealed in the episode "Danger at Ocean Deep" that Parker has an upper-class connoisseur-like taste for fine beverages as he manages to pilfer a bottle of vintage 1998 champagne, right under Penelope's nose no less, and swap it with pure tonic water without her knowing anything. During the launching of the ship he and another fellow chauffeur, a friend named Stevens, share in drinking the entire bottle together. Penelope later finds Parker asleep and hiccupping. A slurring Parker then (drunkenly) reveals his theft. He says he did this on the grounds that it was such a good year it seemed a shame to see it go to waste.
