Triple-use bag: (1) pop a film in it and send it off for processing;
(2) throw up into it; or (3) use it as a scorecard for a game of gin
rummy. Uses (1) and (2) are mutually exclusive, but either can be combined
For (1) and (3), provide your own film or playing cards. TWA's cabin
crew are pleased to supply food to make (2) possible.
