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.

"That's what I'd like to know. The cash drawer's been short three mornings running, and I'm not the sort to blame a cat." "Maybe we should check the lock before the first customers arrive."
