What's in an inch? Apparently, enough missing meat and cheese to cause an uproar. Subway, the world's largest fast food chain with 37,000 locations, is facing criticism after an Australian man posted a picture on the company's Facebook page of one of its famous footlong sandwiches next to a tape measure that seems to show it's just 11 inches.

The New York Post conducted an investigation that found four out of seven footlong sandwiches were shy of the 12 inches that makes a foot.

A spokesman for Subway, based in Milford, said the length of its sandwiches can vary slightly when its bread, which is baked at each Subway location, is not made to the chain's exact specifications.
