Chassidim in Lubavitch would customarily wear long jackets. One chassid, however, wore a short jacket when he was in Moscow on business, and changed into a long jacket when he returned home to Lubavitch.
Once, before entering into a private audience with the Rebbe, Rabbi Shmuel of Lubavitch, the chassid deliberated: ‘Why should I wear my long jacket for my private audience with the Rebbe? The Rebbe knows who I am. Why try to fool him? I will be myself!’
Thus, the chassid entered the Rebbe’s study wearing a short jacket.
“Why are you wearing a short jacket?” the Rebbe asked.
The chassid was shocked. He explained honestly, “Rebbe, I did not want to fool you!”
“Fool me?” the Rebbe asked. “Until now I thought you were a chassid trying to fool the business world. Now I see you are a businessman trying to fool the chassidim.” ~ Heard from Rabbi Shloima Zarchi as quoted in Chicken Soup to Warm the Neshama
