On any trip the crew are allowed to drink any amount of water, soft drinks or juice. Many times on a ten hour sector I may choose to ask for a cola and a glass of ice or any other beverage (non alcoholic of course), what if I elect not to drink it at the time and place it in my flight bag, this is a drink that I'm entitled to and permited to have but decide to defer it til I reach the hotel. Does it make me a thief to take it off the flight with me ? or is it preferable to pour it down the loo. What about the crew meal you dont feel like eating at the time , but save for later, does that make you a thief? Perhaps the Air Canada people are looking at large scale theft and the selling of company stores, that I can understand, but not taking a Coke or a snack off for later consumption.
