In the final scenes of Dead is Forever (#2.6) Col. Aiden Dempsey takes a bottled drink from the chiller in the office building and says 'Cheers young man' then turns to the troop to say 'He was just starting to shape up' before he lifts the bottle to his lips to drink without taking the cap off.
Just after Captain Macalwain is shot by Henno Garvie, Colonel Dempsey tries to drink from the Coca Cola bottle while it still has the top on.
