A lawyer's dog, running about unleashed, beelines for (直奔)a butcher shop and steals a roast. Butcher goes to lawyer's office and asks, "if a dog running unleashed steals a piece of meat from my store, do I have a right to demand payment for the meat from the dog's owner?" The lawyer answers, "Absolutely."
"Then you owe me $8.50. Your dog was loose and stole a roast from me today."
The lawyer, without a word, writes the butcher a check for$8.50.
Several days later the butcher opens the mail and finds an envelope from the lawyer: $20 due for a consultation.
