I have worked many, may Catholic school fund raising fairs and I daresay that ever single one of them has alcohol and gambling. The most successful ones promote it wantonly and shamelessly. One of the smaller schools sets it up where the beer and wine booths surround the biggest gambling booth which is 20' X 20' playing on all sides and no age limits. They will make $200K on that booth alone in one weekend!
Hey, its all good. Its for the school/Church. Besides, once you confess its all forgiven!
