It is narrated from Abdul A'la that Imam Hasan al-Basri, may Allah have mercy on him, entered the market. He bargained with a man over the price of a cloth, so the man said: "For you, it is for such-and-such (price); by Allah, if it were anyone other than you, I would not give it at this price." Imam Hasan, may Allah have mercy on him, said: "Why did you do that?" After that, he was not seen buying or selling in the market until he met Allah, the Exalted.

Brief Explanation
(Commentary on Hadith 590)
Observe the piety and God-consciousness (taqwa) of Hasan rahimahullah: he could not tolerate that, due to his knowledge and status, anyone would show him favoritism or that a price would be set for knowledge.
