Rav Elefant related that he had a talmid who got married and he paid for the wedding. The father told him that he wanted Rav Chaim Shmuelevitz to be mesader kiddushin.
Rav Elefant said "I am paying for the wedding and you get to decide who gets kibbudim? No way. I am going to take the kibbud for myself."
What could the father do...
At the chuppah it was called out "Rav Elefant is mechabeid Rav Chaim Shmuelevitz with siddur kiddushin".
