the lawyer and butcher

A lawyer's dog, running about unleashed, beelines for 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 [attorneys don't carry cash -- it's too plebeian -- and the butcher hadn't brought the shop's credit card imprinter to the lawyer's office].

Several periods of time later -- it could be the next day but that would be unrealistic -- the butcher opens the mail and finds an envelope from the lawyer: $20 due for a consultation.
