Dr. Pepper, A girl’s father is _supposed_ to give a faher to the potential son-in-law.
Which reminds me. A godol (I forget which) gave a faher to a potential shidduch for his daughter. He did very well. Nevertheless he decided to give a second faher to be sure, prior to allowing the shidduch to go through. The bochor said no problem, but if you want to faher me a second time I will need to first faher you. He then demonstrated from the meforshim that he is supposed to marry a bas talmid chochom and has a right to verify as such. The first faher the potential father in law is given rights to, altz derech eretz, even though it is the bochor who has the greater obligation to marry a bas talmid chochom. But before he can administer a _second_ faher, now he has a right to first faher the girls father to insure he is marrying a bas talmid chochom!
I don’t recall if he said this pshat altz a little joke or was serious. Either way the godol called off the shidduch.
That bochor became the Chasam Sofer (I believe.)
