If there's one thing we've all learned in 2017, it's don't mess with Wendy's Twitter account. You will get burned. They're the J.K. Rowling of fast food chains. Just ask Hardee's, a competing fast food chain who tried to get into it with Wendy's on Twitter. Although they're probably not ready to talk about it yet.
The beef started with an innocuous argument between customers over who has a better "4 for 4" (4 items for $4) deal, Wendy's or Hardee's. Then Hardee's got involved.
