Suffice to say, Ambrose had a rather unique appraisal method--he tried guessing the cost of a single plank of wood, then began counting the planks. He then noticed the paint on the wood; and after guessing the price of that, began to count all the planks that had paint on them. Then he noticed a few pipes here and there for sewage, and he tried estimating the cost of those--
Suffice to say, it didn't work.
As "very heartened" he was by the Torchic's work ethic, Malt found it within everyone's interest to give him some new duties.
