The brown rolls were skunks. The box was dropped in the vault of my bank and some rolls broke. My teller re-rolled those in brown wrappers.
Getting shorted will add insult to injury.
Oh well. This was bound to happen. I don't want it to happen to anyone else, so I only dump in machines. Sure the next person searching MWRs of my dumped halves will be skunked, but at least there is hope and maybe the courier's hopper will have some silver sprinkled in.
