Many waiters consider a 10 percent tip an insult, but in a federal lawsuit over the $2.6 million sale of Downey’s Restaurant and Bar in Philadelphia, the plaintiff is likely to be thrilled with his award of a 10 percent commission for finding the buyer.

In an 11-page opinion announcing his verdict from a nonjury trial in Domico v. Downey, U.S. District Judge Berle M. Schiller, of the Eastern District of Pennsylvania, decided that both the buyer and seller had improperly stiffed Robert Domico, and that he is entitled to a commission and fee of $150,000 plus interest for his work in making the deal happen.
