Lots of angry customers felt like they were getting short changed out of that mysterious missing inch.
But it appears that it's not just the bread that's shrinking.
Kaylee Osowski and Natalie O'Neill at The New York Post spoke with a Manhattan Subway franchise owner who told them that bread's not the only Subway item that comes up short.
The owner told the Post that Subway shops have reduced their cold-cut sizes by 25 percent in the past few months.
“The distributor has increased the food cost on the individual owners by 4 to 5 percent every year and provided the owners with less food,” the owner said.
As for that missing inch, Subway said that "SUBWAY FOOTLONG" is just a brand name and is "not intended to be a measurement of length."
