NEW YORK (AP) — What's in an inch? Apparently, enough missing meat, cheese and tomatoes to cause an uproar.

Subway, the world's largest fast food chain with 38,000 locations, is facing widespread criticism after a man who appears to be from Australia posted a photo on the company's Facebook page of one of its footlong sandwiches next to a tape measure that shows the sub is just 11 inches.

More than 100,000 people have "liked" or commented on the photo, which had the caption "Subway pls respond." Lookalike pictures popped up elsewhere on Facebook. And The New York Post conducted its own investigation that found that four out of seven footlong sandwiches that it measured were shy of the 12 inches that makes a foot.
