Rev. Morris Gray in E. Liverpool, Ohio wants to get home already to make Kiddush... And he has Reb Chaim Brisker on his side!
Rev. Gray says that in בריסק דליטא they would announce in all the shuls in the name of Reb Chaim that davening finish NO later than 12 o'clock NOON! I would imagine they didn't start at 9:30, true, but how early can you start already? 6:30? 7:00? Still not what goes on in some shuls today.
