Where, in an action on a broker's contract for the sale of real estate, he alleged that after undertaking the sale for defendant he reported to him that he had a purchaser who had offered him $5,000 in cash to bring about the purchase, and that defendant assented to plaintiff's acceptance of the joint employment and stated that it would in no wise interfere with their contract, the petition was not demurrable as showing a forfeiture of plaintiff's right by his acceptance of an inconsistent employment. Shropshire v. Adams, 40 Tex. Civ. App. 339, 89 S. W. 448.

A petition to recover broker's commissions which shows that plaintiff acted for both parties is demurrable, unless it also alleges that the dual relationship was known and assented to by both. Skrvin v. Gardner, 129 P. 729, 36 Okl. 613.
