The people who work here are the sort of people who don't, and that's intentional. Enjoy the things that are provided, but understand the context and intent behind them and don't abuse them. We get to have these things because we collectively take responsibility for not abusing them. That's how you avoid the tragedy of the commons - if everybody abused them then we'd have to stop having them so freely available.

I've often taken a drink or a snack from the office for later in the evening or the next day. Never considered that this might be frowned upon. On the other hand, taking large quantities of items frequently seems like an abuse of a perk.

I don't think any company would ignore pilfering on a large scale (everybody doing it). Now, large companies might have an office or two which deviate from the norm and may tolerate it a bit, but company-wide, I don't think so.

I don't. My coworkers don't. I rarely see people in my building doing that.

That's the problem with universal quantifiers, they are so easily disproven.

Yeah, personal morals are silly. Throw Snowden down the well.
