thank you so much :)
they might've been intentional -- the cashier's dialogue, for instance, kind of reads like a typo, because he's reciting a permutation poem (or reading from all possible permutations of words in a given sentence)
the idea was that this might be a hint for the verse he needed, as his is one that isn't exactly grammatically sound.
but i've heard the confusion sentiment from a few folks, so i must chalk that up to an experiment that didn't quite pan out correctly ;-)
thank you for your kind words & feedback, & for playing our little game. <3
