A doctor and a lawyer were talking at a party. Their conversation was constantly interrupting by the people describing their diseases and asked the doctor for free medical advice. After an hour or so, the angry doctor asked the lawyer, “How do you do to prevent people asking you for legal advice when you’re out of the offices?” “I give it to them,” replied to the lawyer, “and then I sent them a bill.” The doctor was shocked, and agreed to have a try. The next day, still feeling slight guilty, the doctor prepared the bills. When he went to the place them in mailbox, he found a bill from the lawyer.
