The dog and the butcher

A dog ran into a butcher shop and grabbed a roast off the counter. Fortunately, the butcher recognized the dog as belonging to a neighbour of his. The neighbour happened to be a lawyer. Incensed at the theft, the butcher called up his neighbour and said, "Hey, if your dog stole a roast from my butcher shop, would you be liable for the cost of the meat?" The lawyer replied, "Of course, how much was the roast?" "$7.98." A few days later the butcher received a check in the mail for $7.98. Attached to it was an invoice that read: "Legal Consultation Service: $150."
