davidcyclebackIf your friend says he's mad because you bid against him, tell him you're madder because he bid against you. If he says, "But I bid first," you should say, "As a friend, you should have removed your bid when you saw that I wanted the lot."
When it costs him money as a seller, this mad friend probably would be against the practice of friends refraining from bidding against friends.
