Feeding Frenzy is a solution to the problem of having excess gift certificates or vouchers to local restaurants that do not fit into packages and lend no panache as silent auction items.
The auctioneer sets the stage for the Feeding Frenzy: quite simply, one-by-one, these gift certificates become prizes to the first person/paddle that the auctioneer sees. It is used early in the evening to get people bidding and to do extreme things in public to be noticed. No money is raised but the the game gets the crowd warmed up and bidding.
