One of the biggest threats to you're existence in Stalinist Russia was you're fellow citizen. The "diligent "crewmember on that flight would have been quite safe in such a regime, until the of course, the zealot replacement arrived.
For anyone to condone the actions of the employer and the informer is really just a representation of the climate of the state. To have ones livelihood and potentially future prospects ruined for consuming a discarded sandwich is grotesque.
We still live in age where children are being bombed out of existence, where atrocities are committed and condoned by state authorities......and people get people sacked for eating a f***ing sandwich.......!!!!
