Is your name Jason, Crystal, or Richard? Good news: Lunch is free at Firehouse Subs on Friday!

Firehouse Subs is giving away a free medium sub on Dec. 13 with any purchase as part of its Name Day giveaway. Anyone with the selected names of the day just needs to show a valid photo ID at participating restaurant locations to score the free sandwich.

“Just our way to thank our name,” the company said, which began the promotion on Dec. 9.

On Thursday, the customers named Amanda, Carlos and Christopher got to enjoy a free sub on the house.

The name of the day will be posted on Firehouse Subs’ website, as well as its Facebook and Twitter accounts.
