Minneapolis-based grocery retailer Rainbow Foods has turned the tables on Cub Foods' accusation that the suggestion of a wrestling match to solve a corporate dispute "trivialises" its allegations, by stating that the match should be conducted for charity. Rainbow president Tom Dahlen challenged his counterpart at Cub Foods, John H. Hooley, to a wrestling match, dubbed the "Rainbow Rumble", after the latter company filed a lawsuit last Friday, alleging that Rainbow was receiving Cub's special offer advertising information in advance.
