In other words.. most nights at most clubs (and this happens around the world, believe it or not
). On other nights, there'd be structured events - leagues, club tournaments, etc. Once in a while they'll organize an actual open tournament, print fliers, send out notifications to other clubs, etc. I doubt booze and partying have anything to do with it..
From my experience with American clubs, the evening usually starts around 7 or 8pm, and people stay until 1 or 2 am, way after all the bars have closed, so people usually just head straight home to shower and go to sleep afterwards... Iskandar
