Who gets to decide where food stamp recipients can use their subsidy?  Do fast food meals count as a necessary food purchase?

As the economy continues to languish, the fast food industry is seeking food stamp customers as a potential new source of revenue.

The number of businesses approved to accept food stamps grew by a third from 2005 to 2010, U.S. Department of Agriculture records show, as vendors from convenience and dollar discount stores to gas stations and pharmacies increasingly joined the growing entitlement program.

Who's in already?

Louisville-based Yum! Brands, whose restaurants include Taco Bell, KFC, Long John Silver's and Pizza Hut, is trying to get restaurants more involved, federal lobbying records show.

While you can argue the morals of food stamp programs, you can't deny the potential windfall for the restaurant industry.
