If you had your heart set on a free 6-inch sandwich from Subway today, you may want to brace yourself.

This picture's been shared by thousands of hungry Facebookers, but it's all a lie. Well, sort of.

You see, Subway IS giving out free 6-inch subs to people who buy a large drink...in the United Kingdom. Yes, the UK, not the USA. They're 15.24 centimeter subs.

We hate to be the ones to break it to you, but it's not all bad news. This month, Subway restaurants right here at home are offering any foot-long sub for $6.
