This topic is interesting.
A couple of years ago, I was extremely poor (new job meant relocation costs had me sleeping in my car in a regional town until first pay day). I didnt advertise this at the time (was embarrasing), but a few of my crew clicked on.
I got home one night after 5 sectors (to the quiet spot I had found on the side of the road) and discovered two sick bags full of cheese and biccies in my bag. (not quite as bad as chappelles case I know)...
At the time, I wasnt eating outside of work (couldnt afford it), so the only meals I had were the ones i could scavange on the plane at work.
I worked for a pretty relaxed company - but if someone else puts it in my bag is it theft?
I did learn my lesson about taking crew meals home a couple months later, when the thai chicken noodles I took home (when i had a home finally) and reheated for brekky gave me dreadful food poisoning which saw me pulled off duty upline, and collapse in a taxi. (the hotel manager and cab driver carried me up to my room!).
