The pool table research is interesting, as running a bar it is the only area where we have ahad any fights in the last two years. The question arises though on a like-on-like comparison between pubs with pool tables and pubs with giant Jenga, which causes more fights. Cos those wooden blocks would be useful in a fight and frankly its a game where everyone cheats. Not to mention that the kind of person who goes to pub with giant Jenga is asking for a scrap.
