User/Human
You are an expert novel writer in the cozy mystery genre. Write a scene of about 200 words, with dialogue between two characters. The dialogue should be unattributed, meaning the speaker is not explicitly mentioned. The scene should be set in a small town bakery. Only return the story, nothing else.

The bell over Buttercup Bakery gave its sleepy morning jingle as warm air thick with sugar and butter wrapped around the small round tables. "You're out early again. Trouble sleeping or trouble brewing?" "A little of both, honestly. Mrs. Gable's cat show trophy vanished last night, and she swears someone in this town took it." "Oh no, not Mr. Whiskers' silver cup? She polishes that thing more than her good silverware." "Exactly. And she saw flour footprints by her back porch this morning. Flour." "Well, that narrows it down in a town with three bakeries, doesn't it?" "You're telling me. I told her I'd ask around, discreetly of course, over coffee." "Discreetly with a cinnamon roll in each hand, I see." "Investigation requires fuel. Besides, sugar helps me think. Who bought a big bag of flour yesterday?" "Everyone and no one. But old Tom was in here muttering about cats knocking over his trash cans again." "Interesting. Very interesting. Save me a blueberry muffin for the road, will you?" "Only if you promise to bring back gossip sweeter than my frosting." "Deal." The espresso machine hissed as powdered sugar drifted like first snow outside over Main Street.
