Clever
Your servant uses a stool to break open shellfish. You know how much work shucking shellfish is so this method is really clever.
You knew hiring this servant was a good idea. "Clever girl," you say, as your servant sits on some shellfish again.

"More clever than you!" your servant yells, tearing off his wig. "It is I, Ken (けん) the samurai. I saw you take this shellfish from my master's lands."
You thought you were being so clever, taking shellfish from someone else. It turns out, there is a cost for being shellfish.
