It would be a massive oversight to make any list of fast-food Twitter feuds and not include Wendy's. While the chain has engaged in countless Twitter spats, the fresh beef incident stands out because of its long-term impact — on and offline.
The argument began when a Twitter user asked Wendy's how it delivered its beef "raw on a hot truck." Wendy's responded: "Where do you store cold things that aren't frozen?"
When the Twitter user tried to change the topic to McDonald's, Wendy's attacked.
"You don't have to bring them into this just because you forgot refrigerators existed for a second there," Wendy's tweeted.
The tweet went viral and had a massive impact on Wendy's strategy. Wendy's 2017 Super Bowl ad took inspiration from the tweet. In 2018, the chain reignited the fresh-beef battle, slamming McDonald's for not rolling out fresh beef in all of its products.
