He was in the bathroom with audio & video on.
He gave lots of sound effects with the phone maybe laying on the sink.
After he flushed, he looked at his phone an saw he had the two options on...and turned them off.
Like that Leslie Nielsen bit in that Naked Gun movie, when he went in the restroom at a function and peed on his shoes with his lapel mic still on........
My boss was doing shots on a call with 5 others he didn’t think we could see him hiding it behind his coffee but the second one he must of forgot to hide it. LOL
