Oh my, I'm so sorry Guinevere! You're right, of course. And I checked the quote at least 3 times before posting that answer...
You got the quote and the characters right so the thread is yours.
But, to be exact, these lines were spoken by Farmer Giles to Chrysophylax. So this quote indeed exists twice, though the wording isn't identical (Chrysophylax' words were: Excuse my asking, but were you looking for me, by any chance?).
Please carry on,
Guinevere!
