TGI Friday's Now Lets You Tweet Free Burgers To Your Friends

TGI Friday's is trying to lure millennials back with free burgers. The casual restaurant chain just announced a new promotion called "Buy a Burger, Give a Burger," which allows customers who have just bought a TGI Friday's burger to tweet a promotion code for other people to snag free burgers. The first Tweep who clicks on the social media coupon gets a free burger at any Friday's location.

"You promote because you're chasing guests and you want them to try you," CEO Nick Shepherd told Bloomberg. "We wanted to connect with younger guests to come and try Friday's and see that it's something different."

After a 1.5 percent sales slump last year, this is the latest effort on the part of TGI Friday's to remain relevant in the eyes of 20-somethings. Last summer, Friday's caused a stir by offering completely unlimited appetizers for $10, which caused an uptick in younger customers. Earlier this year, Friday's announced that happy hour was extended to all hours, with rotating drink and appetizers specials every hour.  

"We have to be something worthy of a conversation," Shepherd told Bloomberg.
