I've been called up a few times over the decades.
The first case over 30 years ago when we lived in Colorado. Sat in the jury room as they called groups of potential jurors for various trials. They got to a group that included me and excused us as the defendant had plea bargained to a lower charge.
The next was a drunk driving case when I lived in California. The defense attorney darned near tried his case during jury selection. He claimed that the prosecution was going to bring up the fact that his client was in a part of town that none of us would be in (red light district?) and could we put that aside. I'm an engineer and I thought I could flow chart this in two questions. Question #1 - at the time of the incident was the defendant in command of a motor vehicle? If yes, go to question #2. If no, he's innocent. Let's go home. Question #2 - at the time of the incident, was the defendant under the influence? If yes, throw the book at him. Let's go home. If no, he's innocent. Let's go home. Did I miss something? Oh, and the jury was impaneled before they got to me. Short day.
The third time was also in California. Eviction for non-payment of rent. My name was drawn from the hat first and the first 12 names drawn wound up being the jury. They didn't excuse anybody. The judge and the lawyers couldn't believe they had just done that. A day and a half of testimony, during which everybody on the plaintiff's side told the same story and NOBODY on the defendant's side told the same story. Including the defendant, who contradicted himself. I was elected foreman of the jury and we spent more time eating the donuts the judge left for us in the jury room than we did debating the verdict. We found for the plaintiff. It was simple and straightforward.
The last time was here in Olympia. The judge came to where we were waiting, explained that the defendant had plea bargained at the last minute, apologized for wasting our time and excused us. He said that a lot of defendants do that. They wait until the trial date, realize that the DA is serious about prosecuting them and plea bargain. Wastes a lot of people's time and money. But, that's the system.
I've also been on the pool for a higher level court, but didn't have to drive up to Tacoma.
All these happened when I was employed and it didn't cost me anything. Now that I'm self-employed the cost to me could be higher. But, I'll still serve. It is a duty of citizenship.
