Commentary for Kiddushin 99:14
וצריכא דאי אשמעינן גבי קידושין במקום דלקורבה קאתי בהאי אתרא רחמו לי ולא ממלי מילי עלוי בהאי אתרא סנו לי ממלי מילי עלוי אבל גבי גיטין דלרחוקה קאתי אימר לא איכפת ליה

Daf Shevui to Kiddushin
But when it comes to divorce, he would not care if people like him or not, therefore he might not care where the agent delivers the get. Thus we needed a mishnah to teach us that even with regard to gittin, if he says “give my wife a divorce in such and such a place” the get must be given in that particular place.
