room for improvement

Yesterday, at work (no, not the good writing/drawing/painting work, the bad work that I haven't mentioned here before; the one that involves spreadsheets, meetings, and me sighing every half hour) we received a Business Reply envelope full of rocks. I mean, really full, like I can't believe the US Postal Service would deliver it, full. And included with the rocks was a customer satisfaction card. It was not filled out.
