I won the bet

[Zoochy]

A1 gets fouled in the process of throwing the ball towards the wrong basket. The ball goes in the basket. Partner says to count the basket. I say NO basket. He says "I think you are wrong".. I tell him "The difference between you and I is that, you think I am wrong and I know I am correct!" He won't let it go, so he bets me dinner and shakes hands. Then tells me he likes steak!
After the game I get out the case book and read him case 4.41.2. He is still in denial. The other partner laughs and tells him he owes me dinner.
