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 sub is just 11 inches.

More than 100,000 people have “liked” or commented on the photo, which has the caption “Subway pls respond.” Lookalike pictures have popped up elsewhere on Facebook. And 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.

By Thursday afternoon, the picture was no longer visible on Subway’s Facebook page, which has 19.8 million fans.
