Ah, Sabrina ...

Question: Why don't we let Sabrina eat spaghetti at a restaurant?

Answer:
a) I am not willing to let her ruin her cloths and making her go topless in a restaurant would violate the "shirts and shoes required" rule.
b) They do not have bathtubs available for a complete wash, including shampoo, immediately following the meal.
c) If I am going to pay to have floors or carpets cleaned, they will be mine.
d) All of the above.
