Free Advice with A Twist
A doctor and a lawyer are chatting at a cocktail party, but the doctor keeps getting interrupted by guests looking for free medical consultations. Annoyed, the doctor asks, "How do you handle people pestering you for free advice outside the office?"
"Simple," the lawyer says. "I give them the advice, then I mail them an invoice."
The doctor decides to try it. The next morning, as he’s writing out bills for the party guests, he checks his mail. There, sitting on top of the stack, is a bill from the lawyer.
