NEW YORK (CBSNewYork) — James Dolan’s temper flared up at Madison Square Garden on Sunday, and the result was an ugly scene, the New York Post reported.

The President and CEO of Cablevision Systems Corporation and executive chairman of The Madison Square Garden Company fired a security guard on the spot for not knowing who he was during the Knicks’ contest with the Celtics, according to the newspaper.

Dolan was attempting to enter the Delta Sky 360 Club when security guard Fiordaliza Hernandez asked to see some identification, according to the Post.

“Do you know who I am?” Dolan reportedly asked Hernandez.

The guard said that she didn’t, which led Dolan to ask her how long she’s been an employee at MSG.

Hernandez told Dolan that she’s been working at the Garden for three years, to which Dolan reportedly replied, “I’m your boss! I pay your salary!”

But despite his rant, Hernandez didn’t allow the boss to enter the premises because he didn’t have any identification, the newspaper reported.

“Give me your ID! You’re fired,” Dolan hollered, sources told the Post. “I have to get new security in this building! I have idiots working here!”

Following the uncomfortable and unfortunate incident, Dolan allegedly reconsidered his decision and rehired Hernandez. According to the newspaper, she was again working security at the arena on Monday night when the Rangers hosted the Winnipeg Jets.

Hernandez couldn’t be reached for comment by the New York Post, but MSG spokeswoman Kim Kerns told the newspaper, “As a company policy, we do not comment on employee matters.”

One source with knowledge of the inner workings of Madison Square Garden management, however, told the New York Post that “nobody was fired.”
