Apparently, "someone" (unclear if they were otter, human, or seagull) ate a pack of raw mussels they got from the grocery store and left all the shells at the bakery café.
it pretty much has to be, otherwise there's no money left to pay with.
bet you're the guy that goes bare feet in public and eats mussels at the bakery as well.
Bet that sounded more insulting in your head, didn't it?
