Did they have candlelight suppers, too?
Class snobbery isn’t limited to the wealthy, and can be as much about perceived social class as economic class. Often, snobbery is a form of (sometimes hilariously misguided) imitation of the upper classes to differentiate oneself within and look down upon members of one’s own class.
Depicting your fellow employees as “worker drones” and “farm animals” so disgusting that you can’t bear the sight of them eating certainly makes your declaration that this doesn’t have anything to do with classism unconvincing.
There are perhaps environmental reasons to be concerned about the fact that a fellow worker is saving a few minutes of an already short lunch break by eating a hot meal out of a package container that’s purpose-designed to be eaten out of, but your reasons make it sound like you’re the sort of person whose colleagues are relieved you’re not sharing your lunch break with them (so win-win?).
