Ah you sound like my BIL lol. He always wants to go but hasn't been called ( I think the few times he's gotten a summons they don't call his number even)
I had it oh, 2 years ago I think. Filled out my info sheet, watched a video about being a juror from the 80s, they told us since it was county court it's usually traffic accidents. I had to go up as an alternate while they were picking the jury... it was a kid who had charges of kidnapping, rape, assault

I was the last alternate that didn't chosen, phew! So I got to sleep in compared to a normal day and spent ~2hrs total.
