There was a sikh called Bhai Mona who was serving in the langar of Guru Angad Dev Ji Maharaj. Mona was extremely arrogant and greedy. Some people complained to the Guru the insulting behavior Bhai Mona displayed whilst serving langar. The Guru called him for an explanation. Bhai Mona said that he was the servant of the Guru and would do anything for him and that he was not a servant of the others( sangat). The thief jumped in the fire but was saved by Guru ji's grace. Bhai Mona on the other hand was arrested for the theft of the jewels and was hanged.
