Happens all the time, the type of people judges have to endure is painful.
Unprofessional yes, stupid even, yes. Now go luck under the liberal judge rock if you really want to see mocking and disdain. But we all know the media will never look there, just look at RGB for the example.
Courtroom staff are a team who work together closely day in and day out in a stressful environment. Some frivolity is not necessarily a bad thing if it keeps the team from dreading coming in to work in the morning. Coming into court and dealing with a dysfunctional and unhappy staff is never much fun for the lawyers either, though I suspect that this complaint originates from some pompous attorney who didn’t like it when he found out he was being mocked for his pomposity.
