Julius Scaramonger apparently drunk when encountered by Team 7 of Series 6. Treguard remarks: "They say he's taken to drink since [Ah Wok] opened his mobile emporium. Doing rather well apparently."
Sylvester Hands becoming inebriated by drinking "Old Heggatty's Dungeon Juice Extra Strong Ale" provided by Team 6 of Series 7. A scroll that read 'One for the road... two for a friend.' had hinted that the team would need to offer someone alcohol in order to make them amiable. Lord Fear had cautioned Hands against "boozing it up at The Mad Cow" and commented on Hands' low tolerance for alcohol: "One half of ale, you think you're Genghis Khan; two, you think you're the entire Mongol horde ... I want you sober for the business in hand."
