You are hungry, but there is a bakery near your place, so you go up and leave your home [you are a ratman, and you live in the sewers], following that delicious smell.
“Hello, Mr. Ratman,” says the fine lady behind the counter. “May I help you?”
You can choose one of these answers:
a) Just ask for a classic butter croissant.
b) Ask for the same croissant, and explain to her why you like them so much, perhaps illustrating the point with a humorous or beautiful short story about your croissant-filled past. It’s a small town (but with big sewers!), though, so people don’t mind a bit of small talk.
c) Ask for the croissant, and then go rambling for half an hour about its origins during the Siege of Vienna, and about all the European kings who have ever suffered from lactose intolerance.
