(CBS) – Chicago Mayor Rahm Emanuel was interrupted and shouted down several times Monday night in the first of three town hall meetings scheduled this week to discuss the proposed city budget.

He got an earful tonight about everything from a proposed trash-collecting fee to the closing of a Chicago public school.

Each speaker at Malcolm X College was given one minute for their question or statement. Some  yelled, while some read from their smart phones. One odd man out even thanked the mayor.

Emanuel was unflappable during the sometimes chaotic meeting. At one point, he quipped: “I have three teenagers at home. I’m really OK with this.”

It was the first open budget forum the mayor has hosted since 2011, when he was first elected.

Two more are set for later this week.

The mayor’s office said Emanuel and school officials met with advocates for Dyett High School, who oppose the possible closing of the school.
