NYU Stern professor Scott Galloway was angry with the student for arriving at his class an hour late, though the student did not know about Galloway's classroom policies because he had never taken the class before.
The student, whose name is not known, came to Galloway's 6 p.m. brand management class but was immediately told he must leave.
After the student left, he was angry that he was kicked out, and so wrote the professor an email.
He explained why he was late and believed that he should not have been asked to leave since he was not aware that Galloway kicked out students who were late.
"I was interested in three different Monday night classes that all occurred simultaneously," the student wrote. "In order to decide which class to select, my plan for the evening was to sample all three and see which one I like most. Since i had never taken your class, I was unaware of your class policy."
"I was disappointed that you dismissed me from class considering…it was more probable that my tardiness was due to my desire to sample different classes rather than sheer complacency."
Though the student was probably not expecting much of a response from the professor, he received a scathing one. It soon went viral at the school and has since spread across all social media sites.
In the email, the professor thanks the student for the feedback, then said, "I, too, would like to offer some feedback."
"Just so I've got this straight, you started in one class, left 15-20 minutes into it (stood up, walked out mid-lecture), went to another class (walked in 20 minutes late), left that class (again, presumably, in the middle of the lecture), and then came to my class. At that point (walking in an hour late) I asked you to come to the next class which 'bothered' you."
He ends the email by saying that he hopes "the lottery winner that is your recently crowned Monday evening Professor is teaching Judgement and Decision Making or Critical Thinking. You are an anonymous student who is now regretting the send button on his laptop. It's with this context I hope you register pause…REAL pause (student's name withheld) and take heart what I am about to tell you: get your sh*t together."
