In previous state I was called for jury duty twice, a few years apart.
I ended up on five cases.
DUI twice; stabbing at a county fair; failed equipment in oil well in another state but owner of oil well lived in our fair city and can't remember the other.
Always interesting, educational re the judicial system, fun to meet the fellow jurors....
The oil well case was 3 weeks and we were told that in advance. At the voir dire the questions involved availability for the 3 week period. Many were excused due to the length of the trial.
I don't remember exact pay but it was very low and since I was only working part time my job did not make up the difference.

All of my full time jobs paid you your full salary; ie made up the pay difference.
