 *
 *  Each row carries the two things whoever is typing is least likely to know: what that person is
 *  holding right now, and the size the record last saw them in.
 *
 *  The awkward part is the hand-in: a garment handed back is gone from the person even though the
 *  issue row never says returned, and a copy of this that forgot it would tell a manager a nurse
 *  still holds three tunics she gave back a fortnight ago, and the request she needs would be
 *  declined as over allowance.
 *
