I don't think it is the "teetotaler" view. it is for appearances. Remember this sport is trying to grow and PDGA "states" that is an objective, so for sponsors and spectators seeing a bunch of people walking around and drinking, doesn't really look to good (you don't see people on PBA drinking between frames). It also helps keep the course cleaner during the tournament since there is less garbage to worry about picking up. and this is coming for a heavy drinker
