I've been dutifully separating out the paper recycling in my office for the five years I've worked here. Setting it in a marked bin, only paper, never mixed with other things.

Today I was in my office when the custodian came in and dumped it into the trash with a friendly smile on his face. I asked him, "have you ever put the recycling in with the recycling?"

Still smiling, very friendly. "No."
