We wonder why NYU students refer to him as a "self-important jackass"?

Have you ever spent shopping period class hopping (i.e. sitting in on multiple classes that occur simultaneously)?  One student at NYU’s Stern Business School employed such a strategy during their add/drop period to devastating ends. As he attempted to walk into the middle of Professor Scott Galloway’s course, he was kicked out and informed that late students were not permitted to enter. The student later emailed the professor, insisting that this policy was unfair. Here’s an excerpt from Professor Galloway’s response:

“Thanks for the feedback. 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.

Correct?
