Consultation fees_英语司法笑话

a lawyer's dog, running around town unleashed, heads for a butcher shop and steals a roast. the butcher goes to the 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. the butcher, having a feeling of satisfaction, leaves.

three days later, the butcher finds a bill from the lawyer: $100 due for a consultation.
