NPC: A yak postal worker
Long Desc: A yak loiters here, trying to avoid work.

You stare in amazement at the first non-rabid yak you've seen in these
parts.  However, he still doesn't smell much better than his cousins and you
believe you can detect hints of froth at his lips.  He leans against the
counter and avoids your eye, pretending he doesn't notice a customer needing
service.
He is a buffalo approximately 7'1" tall.
