Did it 2 years ago and loved it.. apart from the waiting around to get a case. Free nosh. Recommend taking something to do like knitting or a book as you can wait all day and not get picked for a case.
I took some fishing line and hooks to tie up. Guy opposite thought I was mad as all he could see was my hands and fingers turning and then me spitting on something (the knot)and then putting something into a little plastic bag.
First case was a major drug bust with 2 defendants, one of which would have reached Australia if someone had given him a JCB,, he just kept digging a hole for himself. What was funny was the barristers in wigs holding their lapels just like a tv drama. Took about 3 days. The next case we got was adjourned so never got to sit on it.
so it will be either dead boring waiting around (and not getting a case) or exciting even humourous and then a little daunting as you decide the fate of someone.(fortunately we don't hang them any more)
