What does this say about us?

I was at Chipotle today, eating a quick lunch before heading up to campus. If you've never eaten there, they make your food and then put it in a lined plastic basket, and when you go to pitch your trash, the trash receptacles very clearly (and in big red letters) admonish you not to throw away the plastic baskets. So I was a little surprised to see a plastic basket in the trash at Chipotle today. Because, really, what does that say about us? Are we so lazy that we can't read and follow simple (large, red) instructions? Or are we so used to our trash-happy lifestyles that we don't think twice about pitching a perfectly fine plastic basket in the trash? Either way, it's pretty unsettling.
