I live in San Bernardino County; each county's rules regarding jury duty differ. When I lived in Los Angeles County, you reported daily for a week and waited and waited and waited. In my present county, it's one day, one case. So hundreds of us lined up for the security check (where they even had me remove my belt???) and filled all the ridiculously uncomfortable chairs...every single one.
I sat for about three hours, give or take, and then my group was informed that our case had settled before we were to be empaneled, so we were excused from further duty, and I went to work.
I feel so ... American!
