A doctor and a lawyer were attending a cocktail party when the doctor was approached by a man who asked advice on how to handle his ulcer. The doctor mumbled some medical advice, then turned to the lawyer and remarked, I never know how to handle the situation when Im asked for medical advice during a social function. Is it acceptable to send a bill for such advice? The lawyer replied that it was certainly acceptable to do so.

The next day, the doctor sent the ulcer-stricken man a bill. The lawyer also sent one to the doctor.
