I've been petitioned to be available for jury duty three times. The first time was for magistrate's court, but I got out of it since it was going to be graduation day for my M.A.
The second time I was given a jury summons number and was told to call the night before to see if I was expected to report. I called, and my number was among those not required to report.
The third time, I did have to report. I sat around all day in a HUGE jury room and was never selected to be on any of the juries called. (I think they called three juries that day.)
