The Holy Rebbe R' Leibel'e Eiger was a huge tzadik and Rebbe but also the grandson of the decidedly non-chasidic gaon Rebbi Akiva Eiger. He once asked the Kotzker if there is a HALACHIC explanation he can offer his grandfather for his davening well outside the bounds of the zmanim mentioned by the Shulchan Aruch [due to his extensive preparations].
The Kotzker told R' Leibel'e to tell his grandfather that the halacha is that when a worker spends all day sharpening his tools, that is also considered part of his job.
