Typically a judge will thank the jurors for their service, and I find the time dedicated to that and the words that honor that service pretty awesome. These jurors truly deserve that respect considering the fear they must have to deal with if someone ever spills their names.
Maybe, but in addition it’s like a social fabric/contract. I don’t want carts everywhere dinging my car up or taking up spaces and because no one else wants that either we all (most of us) tacitly accept to return carts to avoid this problem.
