Oh dear. Oh hell. Oh bother. PI has gotten lost in another staring contest and made things uncomfortable for this stranger. How incredibly impolite!

PI nods to Olympia emphatically and adopts the most deferential posture imaginable. Everything is absolutely alright! To assuage any lingering awkwardness he returns to the waiter and orders two slices of pie. He offers one to Olympia. The other he begins to eat in small bites, being sure to smile continuously at his new friend as he chews, lest she think him impolite a second time.
