Nowadays, it's just as likely that one person will see someone else tweeting about their Frosty/fry endeavors as actually doing it. According to Wendy's HQ, there are an average of 21 tweets per day about dipping fries into Frostys.
"In the digital age, this all kind of took on a life of its own on social media," said BryAnn Roth, Manager of CSR & Brand Communications for Wendy's. "But we really never used it in wide-spread marketing materials… we've never really had to. This is something people are just going to do. They've always done it. And now, they are posting about it."
"The classic diner experience really fueled this. You would order a shake. Your friend would order fries. You guys would end up sharing everything, and naturally the fries would end up in the shake," Hartings said. "Even if there's not a precedent there, it's a very natural reaction, and it's an interpersonal way to eat -- which is usually in a social setting, anyway."
